- Add UserService, DMService, InviteService, BlockService
- Migrate REST handlers (channel, DM, invite, block) to use services
- Remove block_handler.go (merged into dm_handler.go)
- Update all services to accept store.Store instead of *db.DB
- Router creates SQLiteStore and passes to service.New()
Handlers are now thin HTTP adapters: parse request → call service →
map error → write JSON. All business logic lives in the service layer.

Introduce Server/service/ package with MessageService, ChannelService,
and PermissionService that encapsulate business logic previously
scattered across REST and WS handlers. The PermissionService adds
per-user in-memory caching with TTL-based expiry to eliminate
per-message DB round-trips at scale.
Services are wired into the WS hub via deps structs (strangler-fig
pattern) — existing handlers continue to work unchanged, with service
references available for incremental migration.
