refactor(wireguard): drop removed workers field (xray v26.6.22) (#5509)

* refactor(wireguard): drop removed `workers` field (xray v26.6.22)

xray-core v26.6.22 (PR #6287) removed the WireGuard `workers` (num_workers)
config field; the engine now relies on wireguard-go's internal worker
fallback and no longer reads it. Remove it from the panel so it stops
emitting a key xray ignores.

Removed from the inbound/outbound/outbound-form WireGuard schemas, both
WireGuard forms, the outbound form adapter (both directions) and defaults,
the two affected tests, and the `workers` label in all 13 locales. Existing
configs that still carry workers are simply dropped on parse — no migration
needed since the field had no runtime effect.
