v0.319.0: the app page in panels, the login in one place, a password the box never had is said in words

- style A (operator 2026-10-16): hero, tab bar and every section are panels on --bg-1, one width, 16px apart;
  the install page's form groups use the same rule; the settings tab's 700px inner wrapper is gone
- „Belépés az alkalmazásba": name + password side by side, fetched on demand (R-254, R-709); pairing in app_login.go
- the empty-value rule: no stored value -> a sentence, never an eye; page and reveal endpoint share storedValuePresent
- „Cím és kulcsok" is rows (no Domain input, no disabled storage select, no install form); hint under the title
- tests red-proved: app_page_tuning_test.go (4); 36 app-page parity fixtures re-captured, 4 new; install fixtures unchanged
