Deletes Server/store (SQLiteStore, MemStore, the composed Store
interface) and collapses to a single sqlc-backed db package, executing
the prior audit's P4 "single data layer" direction (finding #6).
SQLiteStore was a pure pass-through to *db.DB, so consumers now depend
on narrow interfaces that *db.DB satisfies directly:
- service.Store (service/datastore.go, renamed from store/store.go)
- ws.EventStore (ws/eventstore.go)
- plugin.PluginStore (plugin/pluginstore.go)
The event- and plugin-KV methods that lived in the store's SQLite
implementation move into the db package (db/event_queries.go,
db/plugin_queries.go), keeping their raw-SQL form.
Tests: the MemStore-based unit tests now run against a real in-memory
SQLite db opened per-test with migrations applied, via package-local
seed helpers. Fault-injection tests embed a real *db.DB and override the
single method under test, preserving error-path coverage. Full server
suite and sqlc-verify are green.
Docs: audit finding #6 and A-2026-07-06 marked resolved; decisions D3
updated; architecture server.md / data-model.md diagrams and prose
updated to the api -> service -> db layering.

Service level: BAN_MEMBERS refusal (Forbidden even for nonexistent targets
— no id enumeration), equal-rank and owner-target hierarchy refusals,
authorized ban/unban round-trip, self-ban rejection. Admin API level:
equal-rank owner ban 403s, a lower-positioned ADMINISTRATOR cannot ban the
owner, downward bans still work. All existing NewAdminAPI/NewHandler test
callsites now inject a real ModerationService so the production
authorization runs in every PATCH-user test.
