Merge branch 'dev'

The portal's v2 API replaced nested categories (proclamation_categories.parent_id)
with flat categories plus tag-like groups: a proclamation now belongs to one
category and optionally one group. This lets the Proclamation Options page drop
its special-cased two-level tree.

Database:
- Add the proclamation_groups table (id, name, sort_order) and a
  proclamations.group_id column.
- Drop parent_id from the proclamation_categories DDL so fresh databases get a
  flat table.
- runMigrations() creates the new table/column, then runs a one-time
  transactional v1->v2 migration keyed on PRAGMA user_version: every legacy
  sub-category becomes a group (its id is preserved), proclamations that
  pointed at a sub-category are remapped to (parent category, new group), and
  the now-stale sub-category rows are deleted. selected flags are never
  touched, so user choices survive. No network is needed, so offline kiosks
  migrate at startup; re-running is a no-op.
- Add replaceGroups() and getAllGroups(); stop reading/writing parent_id.

API sync:
- Add PATH_GROUPS ("/groups") and parseGroupsJson().
- parseProclamationsJson() now also reads groupId.
- syncProclamationsFromApi() fetches /proclamations, /categories and /groups,
  leaves the database untouched if any request or parse fails, then replaces
  categories, replaces groups and upserts proclamations.

Proclamation Options page:
- FlatItem is now Category / Group / Proclamation.
- Each category lists only the groups that have at least one member in that
  category, so impossible pairings (e.g. Physical/Prayers) never render.
- Proclamations with no group, or with a group the portal has removed, sit
  directly under the category. Groups are collapsible and use a distinct color.

Tests:
- test_db: groups round-trip plus a legacy->v2 migration test asserting the
  group is created, proclamations are remapped, selection is preserved and a
  second initialize() is a no-op.
- test_proclamation_sync / test_api_client: parse groupId, parse groups, and
  the live smoke test now also fetches /groups.

+
+    ## Authentication
+    The v2 API is **not** API-key gated. The former bearer-token middleware in
+    `src/hooks.server.ts` is present but disabled, so v2 routes are served
+    without a global API key.
+
+    Two endpoints carry their own credential semantics:
+
+    - `GET /api/v2/proclamations` optionally accepts the paired
+      `x-license-key` / `x-email` headers to scope results to an entitled user.
+      Supplying neither returns the full catalogue; supplying only one, or a
+      pair that does not match, is rejected.
+    - `POST /api/v2/automations/create/account` is protected by an HMAC-SHA256
+      request signature (see the operation description).

-# Portal API v2 — current schema
-
-The kiosk talks to `https://portal.radiantwavetech.com/api/v2`. This document
-describes the current contract after the move to an **active/inactive license
-model**. There are no subscription levels: a license is either **valid**
-(subscribed) or not, and the kiosk treats a successful `POST /license`
-validation as the device's "subscribed" flag.
-
-Base URL: `https://portal.radiantwavetech.com/api/v2`
-
-Authentication: `Authorization: Bearer sk_<hex>` on every request (the API key
-is baked into the kiosk binary at build time).
-

-
-## `POST /license`
-
-Validates a license key / email pair.

-Request:

-- `key`: string, **required non-empty** (empty key ⇒ parse failure).
-- `email_address`: string.
-- Any other fields (e.g. the legacy `subscription_level`) are ignored. A 2xx
-  response means the license is valid and the subscription is **active**; the
-  kiosk stores no subscription state other than the `license_last_verified`
-  stamp that drives its 7-day offline grace window.

-Intro
-Some thank you message and introduction to Radiant Waves.
-
-Table of Contents
-
-Setup
-Connect to WiFi
-Connection to the internet is required for Radiant Wave to operate.
-
-Wifi screen appears first
-UP/DOWN to navigate through detected WiFi networks
-Enter to select one
-Password prompt if applicable
-
-I still need to test entering an incorrect WiFi password on a kiosk machine
-Check for crashes or correct error messaging
-
-Email Address
-
-The next screen you’ll be presented with is the email address prompt.
-
-When you purchased your RadiantWave system, you should have received an email at the address you provided during your purchase containing your license key.
-
-Enter the email address where you received your license key here.
-
-Note that you will not be able to enter an invalid email address, but you will be able to enter the incorrect email address. You will see how to change your email address later.
-
-License Key
-
-Grab your license key from your email, now is the time to use it!
-
-A few notes on the License Key prompt:
-You don't have to hold SHIFT or enable CAPS LOCK, because that's already done for you
-You won't have to enter the dashes "-", as those are entered for you
-You CAN enter an incorrect license key
-You CAN fix it later
-
-Same steps as the email address, just type out your license key and press enter.
-
-The Main Menu
-
-Now you're in! This is the main menu, and it doesn't do a whole lot. It's only purpose is to display some system information for you to quickly reference when needed, such as the email address and license key you currently have saved or the current system version you have running. Other than that, the Main Menu's only purpose is to provide navigation between the system settings, and the main attraction itself.
