fix: zamijeni auth polling health endpointom

Dodaje backend /api/health/ endpoint i prebacuje frontend heartbeat sa /api/token/ OPTIONS na /api/health/ GET kako bi se izbjeglo periodicko gadanje auth rute. Dodaje TTL cache za clientStore (lastFetchedAt + force opcija) kako bi se smanjili redundantni crm/clients pozivi pri navigaciji. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
fix: stabiliziraj navbar tranziciju i ukloni white splash

mariomitte	bbdd02c9e9	fix: stabiliziraj navbar tranziciju i ukloni white splash Zadrzava Navbar i ostale UI otoke kroz Astro tranzicije te sinkronizira aktivni path preko astro:page-load kako bi react-spring indikator animirao iz trenutne pozicije. Uklanja bijeli splash pri promjeni stranice i prelasku teme postavljanjem html background boje inline, prilagodbom ThemeToggle logike i uklanjanjem body color tranzicije. Dodano je i TTL kesiranje za dashboard/task dohvat kako bi se smanjili redundantni API pozivi pri navigaciji.
