The copier routine refactor resulted in bad buffer pool handling,
putting a buffer back into the pool twice. This simplifies and removes
the danger prone Upgrade() method.
### Testing
Change the `auditEnabled` option and you should get a prompt in the Web
GUI.
Restart and change the `auditFile` option, and you should get that same
prompt.
The prompt you should get is shown in the screenshots below.

### Purpose
Setting default configuration was not working properly since the
defaults struct is not deeply copied.
### Testing
Try running commands to change default configuration and either inspect
`config.xml` or `/rest/config` result to see the applied changed.
Example:
```
./syncthing cli config defaults folder versioning params set keep 5

feat(gui): close a modal when pressing ESC after switching modal tabs (fixes#9489) (#10092)
Flattened the copier code more. Also removing and moving some
parameters/return values to simplify things. Generally rely less on
return values, e.g. by handling errors right away and using `state` to
do the right thing (e.g. abort on failure).
Supposed to be a refactor without any behaviour changes, except for
fixing a tiny regression on folder order: We used to try copying from
the same folder first, but lost that property at some point (also sent a
PR fixing only that, I'd merge that first making this refactor only).
### Purpose
As stated in #9489 after clicking on a tab link to switch tabs in a
modal you can no longer close the modal through clicking the ESC key
unless you click anywhere on the modal to focus on it again.
### Testing
- Click on a modal that has tabs like "Settings" or "Add Folder" and
switch tabs then click on ESC.
- Check if clicking outside of a modal in the backdrop should still
close the modal.
### Demo

Where `folderFilesystems` and `folders` is built, there's a comment
spelling out the purpose: To have the same folder first, as that's the
most likely to get hits. Plus a copy is possibly more efficient than
from another folder, e.g. if that's on a different filesystem. We lost
that behaviour during some unrelated change.
(Also sneaking in a comment fix on yesterdays change.)
This is a draft because I haven't adjusted all the tests yet, I'd like
to get feedback on the change overall first, before spending time on
that.
In my opinion the main win of this change is in it's lower complexity
resp. fewer moving parts. It should also be faster as it only does one
query instead of two, but I have no idea if that's practically
relevant.
This also mirrors the v1 DB, where a block map key had the name
appended. Not that this is an argument for the change, it was mostly
reassuring me that I might not be missing something key here
conceptually (I might still be of course, please tell me :) ).
And the change isn't mainly intrinsically motivated, instead it came
up while fixing a bug in the copier. And the nested nature of that code
makes the fix harder, and "un-nesting" it required me to understand
what's happening. This change fell out of that.
After opening the database, we performed some checks, such as whether
the migration had already been successfully completed. If so, the
function returned immediately, and the database was not closed.

### Purpose
Fix https://github.com/syncthing/syncthing/issues/9336
The `emitLoginAttempt` function now checks for the presence of an
`X-Forwarded-For` header. The IP from this header is only used if the
connecting host is either on loopback or on the same LAN.
In the case of a host pretending to be a proxy, we'd still have both IPs
in the logs, which should make this much less critical from a security
standpoint.
### Testing
1. directly via localhost
2. via proxy an localhost

This cleans up the option to allow old TLS 1.2 sync connections. The
flag existed for compatibility with old Syncthing versions that don't
support TLS 1.3, which is approximately Syncthing 1.2.2 (September 2019)
and older. ("Approximately" because it depends on the Go version it's
built with and that's when we switched to building with Go 1.13.)
Ref #10062 because it reminded me this exists.

Currently, the "Disconnected (Inactive)" status is only given to devices
that have not been seen for 7 days or longer. However, this is not the
case when adding a new device, or after resetting the database. Those
devices are only marked as "Disconnected", and they will stay like that
even if a long time passes without any connectivity. Moreover, the lack
of an "Inactive" status may confuse the user to believe that their
disconnect is only temporary.
For this reason, always mark devices that have not been seen yet as
"Disconnected (Inactive)".

### Purpose
The `fs.Filesystem` interface contains two parts that cannot be
implemented externally because they are private:
* `filesystemWrapperType`: this PR changes `unwrapFilesystem` to
downcast to a specific concrete type
* `underlying`: this PR simply moves it to an unexported interface
### Testing
Regular tests pass.
This adds a simple delay to the process for starting the pull, by
default one second. In practice this means we're likely to wait for
initial index transfer, or multiple messages sent as part of a larger
change. This is better because we're more likely to have the whole
change for the purpose of handling renames etc, and also it's more
efficient to do one larger puller iteration instead of multiple while
also processing changes.
It does however introduce a certain amount of delay into the sync
process, so it can be tuned down or turned off entirely.
This changes the database structure to use one database per folder, with
a small main database to coordinate. Reverts the prior change to buffer
all files in memory when pulling, meaning there is now a phase where the
WAL file will grow significantly, at least for initial sync of folders
with many directories.

build: replace underscore in Debian version (#10032)
The workflow building Debian packages chokes on branches containing
underscores:
```
{:timestamp=>"2025-04-03T10:31:46.749835+0000", :message=>"Invalid package configuration: The version looks invalid for Debian packages. Debian version field must contain only alphanumerics and . (period), + (plus), - (hyphen) or ~ (tilde). I have '1.29.5~dev.13.ga38df11f~srv_stun' which which isn't valid.", :level=>:error}
```
This replaces the offending `_` with a `~` which should yield a valid
version.
This reduces the number of file entries we carry in the database,
sometimes significantly. The downside is that if a file is deleted while
a device is offline, and that device comes back more than the cutoff
interval (six months) later, those files will get resurrected at some
point.
The current limit is far too low for our workloads. Perhaps we should
aim even higher than the 64MiB this patch proposes?
Citing the sqlite docs:
> [...] after committing a transaction the rollback journal file may
remain in the file-system. **This increases performance for subsequent
transactions since overwriting an existing file is faster than append to
a file**, but it also consumes file-system space.
tl;dr: if the limit is too low, we're shooting ourselves in the foot in
terms of performance.
(v2 change)
This cleans up the command line parsing a little:
- Remove the hack for supporting legacy single-dash long options (e.g.
`-home`), thus enabling actual short options
- Move legacy imperative flags from under the serve command into
separate commands, e.g. `syncthing serve --paths` to see the paths list
is now `syncthing paths`, `syncthing --upgrade-check` is now `syncthing
upgrade --check`
- Add environment variable support for all remaining flags for the
`serve` command (with one exception, left for the reader to discover),
as these are now all modifiers and not imperative

Similarly to #10009, we will remove some discontinued STUN servers,
except instead of being the official primary server, it's some
unofficial secondary STUN servers.
### Testing
Use a STUN client (like [`pystun3`](https://pypi.org/project/pystun3))
to probe that the removed STUN servers are inactive.
