fix: harden salvaged session and browser improvements

Polish salvaged contributor work before PR review:
- read browser inactivity timeout from config with documented fallback
- skip redundant v10 trigram backfill before v11 FTS rebuild
- show delegate_task goals safely in progress previews
- show gateway status model/context without redundant token wording
- wire gateway /sessions to shared session-listing helpers
- map Ravenwolf author emails for release attribution
