This does a *lot* of things. Essentially, it replaces the existing
individual proxy- and autoproxy caches on the bot end with a
global cache (in Core) that handles all the caching at once, and
automatically invalidates the cache once something changes in the
datastore.
This allows us to do proxying and autoproxying with *zero database
queries* (best-case).
Necessary database migrations for this commit:
alter table servers add column log_blacklist bigint[] not null default array[]::bigint[];

The frontpercent command already accepted time patterns (e.g. 9pm), but these were always being interpreted as UTC regardless of the system's configured zone. Furthermore, the time wasn't being nudged to the previous day, so if you tried to do pk;s fp 6pm at 5pm UTC, it would complain about the date being in the future instead of just showing you since 6pm yesterday.
The system zone is now respected and nudging enabled in the same manner as pk;sw move.
The member length limit is now long enough that it's unlikely to
hit the cap by accident. An error will still be displayed if you
attempt to perform a message proxy.
Some of the command rewrite changes resulted in the response messages for importing a system being swapped. When importing without an existing system (ctx.System == null), we want to display the "new system" message. Otherwise, show the count added/modified.
A given system can now have up to 1000 members. Within 50 members of that limit, a warning will display whenever a new member is created via the bot. Once the limit is reached, a final warning will appear indicating that no additional members can be created unless members are first deleted. Attempting to create a new member at that point by any method will result in an error message indicating that the limit has been reached.
Respecting this in pk;import required some restructuring to tease apart which members already exist and which ones need to be created prior to creating any members as it seems preferable to fail early and give the user the ability to intervene rather than pushing the system to the member cap and requiring manual deletion of "lower priority" members before others can be created. One consequence of the restructure is that existing members are being read in bulk which is a performance improvement of 25-70% depending on how many switches need to be imported (the more members you have, the more noticeable this is).
