This simplifies the logic. It also adjusts the position of special
servers slightly; in particular, they are horizontally centered
(appearing in-between the adjacent row, and not merely staggered).
The split into two functions is in preparation for perf improvements
that require calculating this without access to the server.
* Add some re-rendering improvements to avoid the canvas and visual servers getting desynched
* removed underlevelled nerf to low-level servers; improved charisma level docs
* Remove offscreen dynamic culling
* PR feedback; add cache file names to tooltip
* Ensure stasis link servers get loaded properly; ensure darkweb has neighbors to prevent unit tests from failing; remove extra optional chaining accessors
