fix(modules): guard remaining interactive prompts for unattended installs

Audited every module for prompts that would hang an answerfile/unattended run.
The EWW form-factor question and several interactive-config modules were still
unguarded (only hyprlua had been fixed):

- hyprland.sh, niri.sh: skip the EWW form-factor `read` when MARCHY_UNATTENDED=1
  or stdin is not a TTY, defaulting to the desktop/no-battery bar (matches hyprlua).
- mail-notmuch.sh, caldav-sync.sh: install the tools, then exit cleanly in
  unattended mode instead of blocking on the account/server credential prompts —
  the user configures the account after first boot.
- freeipa-server.sh: bail out early in unattended mode; FreeIPA server provisioning
  is interactive and must run on a booted system (ipa-server-install needs running
  services), so it can never run during the install.

freeipa-client.sh is left as-is: it has a genuine --unattended enrolment path.
