fix(mailserver): Use uid/gid 5000 for vmail user in Dovecot config

Browse Source 
Fixes Roundcube IMAP "Internal error occurred" caused by Dovecot
running mail processes as uid 102 (Alpine default) instead of the
actual vmail user uid 5000.

Changes:
- configure_postfix: virtual_uid_maps/gid_maps 102/105 → 5000/5000
- configure_dovecot: mail_uid/gid, first_valid_uid, userdb args
- cmd_add_user: passwd file entries and ownership

- **Fix Applied:**
- `p2p-mesh.sh`: Silenced usage output when sourced as library
- **Tested:** All RPCD methods working via ubus, discovery mode toggle, bulk tokens
27. **Mailserver Dovecot UID/GID Fix (2026-02-25)**
- Fixed Roundcube IMAP "Internal error" caused by Dovecot running as wrong user (uid 102 instead of 5000)
- **Problem:** Dovecot config had hardcoded uid=102/gid=105 from Alpine defaults, but vmail user is uid=5000/gid=5000
- **Files Modified:**
- `mailserverctl`: Fixed 7 uid/gid references (102→5000, 105→5000)
- `dovecot.conf` template: Changed mail_uid/gid, first_valid_uid/last_valid_uid
- `configure_postfix`: Changed virtual_uid_maps/virtual_gid_maps
- `cmd_add_user`: Changed passwd file uid:gid entries
