feat(dashboard): auto-slug app names and infer route host kind from input

Two related polish passes on forms the operator hits most.

App create form: the slug field used to come before the name field and
demanded the operator hand-roll a valid slug. Now the name field comes
first and the slug is derived from it live, GitLab-style — Unicode
NFKD-decomposed, combining marks stripped (so `Café` → `cafe`), `ß`
mapped to `ss`, non-`[a-z0-9]` runs collapsed to `-`, trimmed and capped
at the backend's 63-char limit. The auto-sync releases as soon as the
operator edits the slug manually, and re-engages if they clear it. The
slug input itself runs every keystroke and paste through the same
normalizer, so dirty input never reaches the form state.

Route create form: the three-way host-kind `<select>` plus a sometimes-
disabled input was confusing — operators routinely picked the wrong
kind, typed a host the app didn't claim, and only saw the error after
hitting Create. Replace with a single text input that infers the kind
from what's there (`*` → any, `*.foo.com` → wildcard, `foo.com` →
strict), shows the detected kind as a colored chip beside the field, and
suggests the app's existing domain claims via a `<datalist>`. The same
matching logic the backend runs in `validate_route_host_against_app`
now lives in `route-utils.ts` so the form can surface a soft "not
covered by any claim" warning *before* submit. Path also pre-fills to
`/` so the most common case is one click away.

Lockfile drift from `npm install` (pre-existing 0.5.0 → 0.5.1 version
sync, npm metadata cleanup) is folded in here since it surfaced during
this work.
