Bump react and react-dom 19.1.2 -> 19.2.7 and @types/react and
@types/react-dom from v18 to v19. Keeps babel-plugin-react-compiler,
which is a separate build-time tool, not part of the React 19 runtime.
The @types v19 upgrade surfaced 21 type-only errors, all fixed without
runtime behavior changes:
- useRef<T>() now requires an explicit argument: pass undefined
- DOM element refs are RefObject<T | null>: widen PostFormFields and
AdvancedSettings ref prop types accordingly
- retype reply-modal onInput handler to FormEvent + currentTarget
- add a null guard for the boards-bar search input
- update test mocks for stricter cloneElement/forwardRef typings
Verified: type-check, lint, 1051 tests, and build pass; react-doctor
score unchanged at 54; browser smoke across Chromium/Firefox/WebKit
plus mobile viewport clean.
Accessibility/semantics pass aligned with React Doctor: role-based spans/divs become real buttons, role=status becomes <output>, modals use native <dialog>, author/peer flags render as <img>, and embed/challenge iframes are sandboxed. Includes review follow-ups: correct button chrome/centering/themed dialog colors and focus rings, the missing aria-label i18n keys (all languages), the Yandex image-search URL, clearer .bso setup steps, a keyboard-accessible image-search dropdown, and removal of the post-edit ('comment edited') display (mod edits unchanged).
Board browsing, catalog filtering, post publishing, and reply publishing had little or no honest whole-repo coverage, which let route-level regressions and duplicated form side effects slip through. This pass adds targeted tests for those user flows and fixes the duplicate `PostFormTable` mounting bug they exposed.
Integrate bitsocial-react-hooks#16: replace raw useAccountsStore access with
useAccountSubplebbitAddresses so .eth/.bso aliases are deduplicated under .bso.
