Add personal API tokens; wire measuring tools into remaining surfaces

API tokens: any user mints named, optionally-expiring tokens
(shopdb_pat_..., sha256-stored, secret shown once) at Settings > API
Tokens; a before-request shim swaps a valid PAT for a request-scoped
JWT of its owner, so the entire existing auth/authz/import-mode stack
works unchanged and revoked/expired tokens 401 cleanly. Built for
long-running scripts - the legacy import no longer dies when a login
JWT expires. Migration 7d21_apitokens; create/revoke audit-logged.

Audited integration gaps fixed: Asset.to_dict serializes measuring
tools (typedata + pluginid - relationship links to tools resolve); map
subtype filter/colors and MapEditor include them; dashboard totals
count them; warranty links use a new by-asset route; the measuringtools
ADR-010 hooks are real (corrected presentation token, implemented
map-overlay endpoint); the login avatar resolves through the
employee-photo helper.

737 tests pass; naming green; frontend builds; both features verified
live end-to-end.
