fix(gbp): refresh profiles during sync

[arberx]

What

• Refresh selected GBP location profile fields from the Business Information API at the start of gbp-sync.
• Keep gbp_locations.syncedAt tied to the successful per-location sync transaction, so failed locations are not analyzed as covered by the run.
• Add a regression test that verifies a stale empty description is replaced during sync.

Why

PR #729 added gbp-description-missing, but the signal read gbp_locations.description while gbp-sync only refreshed performance, place action, lodging, and Places data. A location whose owner description was fixed in Google could keep re-emitting a stale missing-description insight until the operator manually rediscovered locations.
