Replace the assetlinks.json placeholder with the Play App Signing key
SHA-256 certificate fingerprint so Android App Links for
https://sauci.app/join/* can verify.

Adds a shareable https://sauci.app/join/{code} link as an alternative to
manually typing an 8-character invite code:
- apps/web: /join/[code] page that validates the code shape client-side,
attempts the app.sauci:// scheme link, and falls back to a large code
display with copy button plus App Store/Play Store links; PostHog events
for page view, code copy, and store-button clicks.
- apps/web: apple-app-site-association and assetlinks.json under
/.well-known so iOS Universal Links and Android App Links can verify
sauci.app for /join/*. The Android release cert SHA-256 fingerprint is a
placeholder pending the real value.
- apps/mobile: associated domains (iOS) and an intent filter (Android) for
https://sauci.app/join/*, alongside the existing app.sauci scheme.
- apps/mobile: parse incoming join links, pre-fill and highlight the code on
the pairing screen, stash the code for signed-out/mid-onboarding users and
apply it once they reach pairing, and offer a once-per-session clipboard
hand-off that is never auto-applied.
- apps/mobile: share message now leads with the join link, keeping the raw
code visible as a fallback.
- Analytics: invite_link_opened, pairing_code_prefilled (mobile);
join_page_viewed, join_page_code_copied, join_page_store_button_clicked
(web).
