fix(Jobs): anchor throttle field regex to prevent id extraction bugs

Throttle POST field parsing used preg_replace with an unanchored
lazy pattern to pull numeric ids out of field names, which could
mis-extract or silently fall through on unexpected key formats.

- Replace preg_replace('/.*?_(\d+)$/', ...) with preg_match against
  an anchored pattern ('/^throttle_count_(\d+)$/' and
  '/^throttle_period_(\d+)$/') in app/Controllers/Jobs.php
- Only process the key when the anchored pattern actually matches,
  avoiding bogus $throttleId values feeding $arraySave/$notToDelete
