The LAN/IIS and Linux templates shipped a placeholder secret printed in the
manual, and installs that kept it signed logins with a public key; any setting
also invited short or reused values (security review F1). The setting is now
ignored (one warning at boot if still present): the server generates a key once
(48 random bytes) into jwt-signing.key in the data folder (beside the app if
there is none; owner-only on Linux) and reuses it, so sign-ins also survive a
restart where the server used to make a new key each boot (standalone, Linux
desktop). If the file cannot be used, a temporary key is used for that run.
Templates and dev launch configs drop the setting; manual updated (key page
rewritten, setting steps removed from install pages); changelog line.
Checked locally: token forged with the old placeholder 401; key file created
and reused after restart (old token 200); auth and 2FA tests pass.
