fix: apply_cell_name regex now matches zone files with TTL field

Browse Source 
_generate_zone_content writes records as "name TTL IN A value" but the
regex only matched "name IN A value" (no TTL), so renaming the cell
never updated the DNS hostname record. Updated regex to make TTL optional.
Also fixed the unit test zone fixture to use the actual generated format.
