fix(providers): don't silently enable rate-limit protection on PATCH unless persisted (#11278)

PUT /api/providers/[id] unconditionally called enableRateLimitProtection(id)
whenever the request body included rateLimitOverrides, even null. Since
EditConnectionModal.tsx sends rateLimitOverrides on every connection save
regardless of whether the operator touched that section, saving any
connection silently started queuing its requests through Bottleneck while
the DB (rate_limit_protection column) and the dashboard toggle both still
showed the feature off.

Only (re)enable the in-memory limiter when updated.rateLimitProtection is
actually true (mapped from the persisted DB row), and explicitly disable it
otherwise so runtime state can never drift ahead of the DB.
