The siege can now auto-open registration on scheduled days/time instead of only
manual /csphase. Schedule is context-owned state (like owner), persisted across
restarts via the same config-JSON path. New GM command /csschedule sets/views/clears
it (e.g. /csschedule Sunday 20:00, UTC). +2 unit tests (11 total).

Castle Siege state was in-memory, so the castle owner (and thus the P4 hunting-map
reward) reset on every server restart/redeploy. Now the context marks itself dirty
on any persistable change (phase transition, registration, owner set); the plugin's
periodic tick writes a snapshot into its own PlugInConfiguration CustomConfiguration
(a JSON blob already stored in PostgreSQL - no schema migration) and restores it on
startup. Battle state (defenses/switches/occupier) stays transient. +2 unit tests.
