* fix(security): read the password-complexity key the settings UI writes
The settings UI saves the admin's complexity choice as
security_password_complexity (useSettingsState.ts prefixes security_ to
password_complexity), but getPasswordComplexitySettings() queried
security_password_complexity_level — written by nothing — so the setting
was silently ignored and password validation always used the 'moderate'
default. Spotted in the filpgame fork (their main, 2026-07-14).
* fix(security): accept the Postgres json-column shape of the complexity value (codex review of #843)
On SQLite the TEXT column returns the JSON-stringified value
('"very_strong"'), but on Postgres (production default) setting_value
is a json column and arrives already decoded ('very_strong') — the bare
JSON.parse threw and the outer catch silently fell back to 'moderate'
again. Parse with fallback, mirroring getAppSetting's documented
pattern; test now covers both driver shapes + the empty-value default.
