Resync Strava title from list payload via Save

Context / Problem: Strava titles can be corrected after import. The sync path only handled new rides; existing rides were marked skipped without checking the cheap list metadata, so corrections like ride #789 stayed stale.

What: In syncRides reuse the existing Save write path for rare title resyncs (pay GPX parse cost) when existing.Name != list.Name; track progress.Updated and surface it in SSE/TS UI; add tests for resync without stream fetch. Remove the now-obsolete TODO.

QA: go test/ vet, tsc, biome/stylelint pass.
