Fetches user_full_name (givenname + sn) and user_email from FreeIPA via
ipalib and writes them into the Thunderbird IMAP account prefs. Adds
ipalib availability check to logon_script.sh. Drops TB_MAIL_FULLNAME
config variable.

Adds SERVERFQDN_IMAP and TB_MAIL_FULLNAME to setup_system.conf.dist.
On each logon the script checks if an IMAP account for DAVTOKEN_USER@TLDOMAIN
already exists in prefs.js; if not it writes the server, identity, and account
entries and registers it with accountmanager. Idempotent — skipped when the
account is already present.
