Persist Open Dental's 'Do not show this window on startup' by making
FreeDentalConfig.xml writable:
- Option A: one-time elevated save
- Option B (preferred): grant Users Modify via well-known SID S-1-5-32-545
- od-cfg-acl.ps1 auto-resolves 64/32-bit install path, iex-safe conventions
- Security note on reversible MySQL password in the config; limited user / Middle Tier
- Cites OD manual freedentalconfig.html / choosedatabase.html
