fix: onboarding persistence, clipboard, install UI, OnlyOffice removal, UI containers

Onboarding:
- Persist current step in localStorage — page refresh resumes where user was
- Router afterEach saves step; guard redirects to saved step, not always intro
- Show npub alongside DID on restore success screen

UI fixes:
- Clipboard polyfill for HTTP contexts (fixes Copy DID crash on non-HTTPS)
- AppCard installing overlay shows for pkg.state=installing (survives refresh)
- Hide uninstall button during installation
- Frontend version bumped to 1.3.2

App store:
- OnlyOffice fully removed from marketplace, curated apps, app config
- Replaced with CryptPad references throughout
- Remove OnlyOffice from ISO capture patterns

Container stability:
- UI containers (bitcoin-ui, lnd-ui, electrs-ui) pull from registry first
- Added --cap-add FOWNER for rootless Podman compatibility
- electrs-ui now included in first-boot loop alongside bitcoin-ui and lnd-ui
