feat: bb_mdns_cache consumer-configured TXT capture via const descriptor (#755)

- add bb_mdns_txt_field_t descriptor (const/rodata) + entry_size/txt_fields/
  txt_count config fields (appended at struct end, back-compat preserved)
- add pure bb_mdns_cache_apply_txt / bb_mdns_cache_txt_serialize (host +
  espidf), mirror functions so stored bytes and JSON output can't drift
- ESP-IDF glue: stack scratch buffer sized to the effective entry_size,
  bounded by new CONFIG_BB_MDNS_CACHE_ENTRY_MAX (default 192); identity
  fields always filled, TXT descriptor applied only when configured
- bb_mdns_cache_start() rejects a descriptor without entry_size, and any
  entry_size exceeding the compile-time cap, loudly (BB_ERR_INVALID_ARG)
- extract bb_mdns_cache_start()'s two guard checks into a pure, host-tested
  bb_mdns_cache_validate_config() predicate (100% branch coverage)
- requery_work_fn's TXT adapter view is now a named constant
  (BB_MDNS_CACHE_REQUERY_TXT_MAX) with a bb_log_w on truncation, instead of
  a silent magic-8 cap
- bb_mdns_cache_txt_serialize gains an entry_size bound mirroring
  apply_txt, skipping (not reading) any out-of-bounds field
- add BB_MDNS_CACHE_ASSERT_IDENTITY_LAYOUT() build-time contract check for
  consumer entry structs
