fix(formatters): localize PR buttons, cap oversized content, dedupe status logic

- PR merge/close button labels now follow the group language (actions.merge/close)
  instead of hardcoded Chinese
- clamp content to Discord embed limits (title 256, description 4096, field value
  1024, 25 fields) in formatters plus a render-layer safety net; Telegram gets a
  tag-safe 4096-char cap (capHtml closes dangling tags)
- raise commit subject truncation from 72 to 200 chars (MAX_COMMIT_SUBJECT)
- extract workflowStatus/workflowRunStatus/statusColorKey helpers shared by
  check_run/check_suite/workflow_run/workflow_job
- dedupe deployment ref/sha fields via addDeploymentRefFields
- commit_comment without a commit id uses title_plain (no dangling ???????)
- tag pushes now report 'Tag created'; zh push title includes the {ref}
- sender profile link derives from the repo's forge origin instead of github.com
- group webhook log emoji injected via emojiPrefix, removed from locale files
- dispatchEvent accepts preloaded groups (single KV read per webhook)
- webhook 401 logs distinguish 'secret not configured' from 'invalid signature'
