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.

The 2FA step matched the user by temp token alone, and the token was left
empty after a successful 2FA login (null right after turning 2FA on), so an
empty or missing token skipped the password step (security review F5).
Now: an empty or missing temp token is refused before the lookup; the token is
cleared to null after success; after 5 wrong codes the token is cleared, so the
password must be entered again (counted in memory per user).
Changelog: general security notice for self-hosted upgrades, and the one
behaviour change users can see. SECURITY-REVIEW.md: F5 fixed.

Also removes the server-only /var/ayanova chown/chmod lines from the Linux desktop upgrade page.
