Fix Dovecot hard restart killing active IMAP/POP3 connections

Browse Source 
Replace 'systemctl restart dovecot' with 'doveadm reload' in
virtualHostUtilities, mailUtilities, and renew modules. The nightly
backup scheduler, SSL operations, and weekly cert renewal were
forcefully terminating all client sessions. doveadm reload applies
config changes (including updated SSL certs) without dropping
existing connections. upgrade.py is intentionally left unchanged
as full restarts are appropriate during upgrades.
