- site/hephaestus.x/index.html: replace single 'Sign in with wallet' CTA with
a <details> dropdown labelled 'Bitcoin Cash wallet'. Menu items:
Sign in -> /user/oauth2/hephaestus-wallet#import
Sign up -> /user/oauth2/hephaestus-wallet#create (pill: easiest)
WizardConnect -> /user/oauth2/hephaestus-wallet#connect (pill: most private)
Same emoji + copy scheme as the wallet accordion, so the landing previews
the choices the user will see after clicking through.
- Hephaestus/auth-proxy/public/wallet.js: renderTabs() now reads location.hash
and auto-opens the matching <details> option on load (create/import/connect).
Fragments survive Forgejo's OAuth redirect chain, so a click on 'Sign up'
from the landing lands the user directly on the Create accordion.
