Feature Proposal: Administrative Account Recovery/Reset in `setup.py`

[parisnakitakejser]

Introduce a dedicated recovery/reset function to the /pgadmin4/setup.py command list to allow administrators to easily recover locked-out accounts directly from the command line without manual database intervention.

Proposed CLI Interface

1. Dedicated Recovery Command (Recommended):

   python /pgadmin4/setup.py recover-user --username <email> [--reset-attempts] [--unlock]
