add API routes, admin UI, and SPA bootstrap

views_api wires the full task lifecycle: create / update / delete /
list (per-wallet, public, admin-all) and the completion flow (claim /
start / complete via POST, unclaim via DELETE, plus a "mine" lookup
for the current user's claim on a task or specific occurrence).

Auth model: tasks are owned by an LNbits wallet but signed with the
wallet owner's account.pubkey — _wallet_pubkey resolves that pubkey at
create time and refuses to create tasks for accounts that haven't
generated a keypair yet, so we never publish a task we can't sign.

Completions optimistically insert with a local hash, publish to Nostr,
then re-insert under the actual event id so a later delete can find it.

Static SPA: Quasar-UMD index.vue / index.js mirroring the events
extension layout — wallet picker, task table, create/edit dialog with
optional daily/weekly recurrence, plus an admin-only public_listing
toggle. /tasks/:id and display.vue intentionally left out until the
public task page lands.
