fix(monitoring): exporter auth and reload fixes

Browse Source 
- postgres: use lib/pq conninfo DATA_SOURCE_NAME; the postgresql:// URL
  form broke on special chars in the password (net/url: invalid userinfo)
- nginx: flush handlers after deploying stub_status so nginx reloads
  before the exporter starts scraping
- valkey: drop invalid +arcount command from the exporter ACL set
  (Valkey aborted startup parsing the ACL file)
