Expose calculateStock on window; add Playwright inspection scripts

scripts/save-login.js: opens a real Chromium window so you log in once and

the auth state is saved to scripts/auth-state.json (gitignored).

scripts/inspect-app.js: headless run that reports the BUILD_ID actually

running in the browser, runs calculateStock(), filters to the items you

pass on the command line, and captures debugStock console output -- so we

can confirm fixes are live without round-tripping with the user.

Also: bump BUILD_ID + cache-buster (v=20260606c) + SW cache (aadhat-v6)

so this round is detectable, and expose window.calculateStock/FirebaseService

to make the inspector work.
