fix: verified map names, param remaps, and write lifecycle test

- Fix tag create: AddTag → CreateTag
- Fix tag update: UpdateTag → UpdateTagColor, param {id} → {tag}
- Fix sync_resource create/update: CreateSyncResource → CreateResourceSync,
  UpdateSyncResource → UpdateResourceSync
- Add GET/DELETE param remapping for tag ({tag}), variable ({name}),
  user_group ({user_group}) — same pattern as INSPECT_PARAM_KEY
- Update api.md with corrected endpoint names
- Add scripts/test_write_lifecycle.py — full CRUD lifecycle test
  covering 15 resource types across 4 tiers, urllib-only

All fixes verified live against Core v2.3.3 error responses.
