Fix discrepancies: use WG_CLIENT_PORT instead of WG_PORT for setup fallback

- Fixed setup/2.post.ts to use WG_CLIENT_OVERRIDE_ENV.CLIENT_PORT instead of WG_INTERFACE_OVERRIDE_ENV.PORT
- Fixed sqlite.ts initialSetup to use WG_CLIENT_OVERRIDE_ENV.CLIENT_PORT for consistency
- Corrected unattended-setup.md documentation:
  - Changed INIT_HOST and INIT_PORT from group "1*" to group "2"
  - Clarified INIT_PORT description as "Port clients will connect to (endpoint port)"
  - Updated group numbers: DNS is group 3, CIDR is group 4, Allowed IPs is group 5
  - Fixed warning text: setup requires groups 1 and 2, and use WG_CLIENT_PORT (not WG_PORT)
- Ensures consistency between code behavior and documentation

+To skip the setup process, you must configure groups `1` and `2`. You can alternatively use `WG_HOST` and `WG_CLIENT_PORT` to set the host and port without using the `INIT_` variables.
 
 Avoid setting both `INIT_` and `WG_` variables for the same setting to prevent confusion.
