xarmian 82e93d6014 feat: implement SSE connection limits ...

Add configurable global and per-workspace SSE connection limits to
prevent memory exhaustion from unbounded connections. Returns HTTP 429
when limits are reached. Logs warnings at 80% capacity.

Configurable via PAD_SSE_MAX_CONNECTIONS (default 1000) and
PAD_SSE_MAX_PER_WORKSPACE (default 100), or config.toml.

Adds WorkspaceSubscriberCount to EventBus interface for per-workspace
tracking (MemoryBus iterates subscribers, RedisBus uses existing
wsCounts map).

Resolves TASK-165
