Paulo Castellano b10f25f94d refactor(posts): tighten content-length caps and simplify contentOverflow
- Platform::contentOverflow returns int (0 = fits) via max(), drops the
  nullable-int + ternary pattern; HasSocialHttpClient and the validation
  rule updated to compare against 0 instead of null.
- Drop the hardcoded 63206-char limit to 10000 across all entry points
  (Platform enum, MCP CreatePostTool/UpdatePostTool, FacebookRules, all
  three FormRequests). Facebook's API accepts up to 63206 but nobody
  writes 63k-char posts and emoji-heavy content risks overflowing the
  TEXT column's 65535-byte ceiling.
- Compiled i18n JSON regenerated with the content_exceeds_platform key.
