Daniel Onyejesi 53a486dbd5 Fix: bump SW cache to v12, switch JS/CSS to network-first
Old pedscribe-v11 cache was serving stale admin.js to browsers
even after server updates. New cache name forces old SW to
deactivate and all clients to get fresh JS on next load.
Also switch JS/CSS from stale-while-revalidate to network-first
so code fixes are picked up immediately.
