fix: post-review fixes for PRs #1311/#1312/#1313 + CHANGELOG

- sdkconfig.defaults.devkitc: header build command idf v5.2 -> v5.4
  (source needs esp_driver_uart, IDF >=5.3 — same reason the PR fixed
  the README refs)
- engine/lib.rs: separate doc comments — set_room_adapter's ADR-150
  adapter/witness doc had merged into set_multistatic_config's doc
- ui: apply stored bearer token at api.service.js module load instead
  of QuickSettings.init — services + dashboard tab dispatch their first
  /api/v1/* requests before initializeEnhancements() runs, so the first
  requests on every load went out without the Authorization header
- CHANGELOG: Unreleased entries for #1308/#1309/#1310
