migrate existing sqlite dbs to the new columns, don't force a nuke on deploy

upgraded containers (like the unraid one with a persistent ./data volume)
kept their old media_items/media_streams tables, so upsertJellyfinItem hit
"table media_items has no column named original_title" on first scan after
the canonical-language rewrite. sqlite has no native add-column-if-not-exists
so we try/catch each alter, same pattern we had before i deleted the shims.

also backports the older alters (stream_decisions.custom_title, review_plans
subs_extracted/confidence/apple_compat/job_type) so pre-rewrite installs
still converge without a wipe.
