fix(https): restore TLS handshake — name hostname + correct PKI path
Closes #10. Two linked bugs in 26.4-alpha's Phase 1 HTTPS made the
force-HTTPS toggle fatal: every SNI handshake on :443 died with
SSL_ERROR_INTERNAL_ERROR_ALERT, so the toggle redirected users from
working HTTP to broken HTTPS.

Root cause 1: bare `:443 { tls internal }` gives Caddy no hostname to
issue a leaf cert for, so /var/lib/caddy/certificates/ stayed empty and
Caddy sent TLS `internal_error` on every handshake. Fix: the :443 block
is now `__FURTKA_HOSTNAME__.local, __FURTKA_HOSTNAME__ { tls internal }`,
with the marker substituted by webinstaller/app.py at install time and
by furtka.updater._refresh_caddyfile on self-update (reads /etc/hostname,
falls back to "furtka"). `auto_https disable_redirects` keeps Caddy's
built-in redirect out of the way of the /settings toggle.

Root cause 2: furtka/https.py and the /rootCA.crt handler both referenced
/var/lib/caddy/.local/share/caddy/pki/authorities/local/ — a path that
doesn't exist. caddy.service sets XDG_DATA_HOME=/var/lib, so Caddy's
storage is /var/lib/caddy/ directly. Fix: both paths corrected.

Verified on the 192.168.178.110 smoke VM by swapping the Caddyfile in,
reloading, handshaking, restoring: TLS 1.3 handshake succeeds, leaf cert
issued under /var/lib/caddy/certificates/local/, /rootCA.crt returns 200.

Tests: new cases assert the Caddyfile ships the hostname placeholder,
the webinstaller substitutes it, _refresh_caddyfile re-substitutes from
/etc/hostname on update, and the asset sets auto_https disable_redirects.
Unit tests still stub the Caddy reload — the real handshake regression
needs a smoke-VM integration test (follow-up, separate from this fix).
