feat: split bb_data_http STATE/EVENT bookkeeping into separately-sized pools (B1-1447) (#1236)

- pool-allocate poll (STATE dirty-mask/seen-gen) and push (EVENT cursor/
  drop accounting) blocks per client at acquire time, gated on
  subscribe_mask, instead of carrying both inline on every client slot
- new BB_DATA_HTTP_MAX_POLL_CLIENTS/BB_DATA_HTTP_MAX_PUSH_CLIENTS Kconfig
  knobs (default to BB_DATA_HTTP_MAX_CLIENTS, byte-identical worst case)
  plus shrink-only bb_data_http_cfg_t overrides, mirroring max_clients
- pool exhaustion fails bb_data_http_client_acquire() cleanly with
  BB_ERR_NO_SPACE rather than ever returning a client with an
  unexpectedly-NULL poll/push
- pins the struct shrink via _Static_assert (120B host / 88B ESP32)
