Extend the wiki's RichTextEditor to the Posts editor and close the
stored-XSS gap on public post bodies.
- RichTextEditor: add `variant` prop — `full` (wiki), `post` (no
internal wiki-page link picker), `minimal` (image-only, for
Screenshots captions). Toolbar sections rendered conditionally.
- PostEditor: replace the body textarea with a lazy-loaded
RichTextEditor in Suspense; variant chosen by category
(minimal for screenshots, post otherwise).
- posts.model: sanitize body via shared cleanBody on create/update,
treat an empty TipTap `<p></p>` as null, and auto-derive the
excerpt from the body (max 280 chars) when left blank.
- sanitizeHtml util: add deriveExcerpt() helper.
- FiveOnFriday / NewsletterIssue: wrap dangerouslySetInnerHTML with
DOMPurify.sanitize() as defense-in-depth on render.
No schema or dependency changes. Verified end-to-end against the
local stack: 24/24 API assertions and a full UI round-trip across
all four post categories.

Foundation & safety phase of the wiki upgrade (see WIKI_UPGRADE.md).
Schema (additive, idempotent via ensureSchema):
- new wiki_categories table; wiki_pages gains category_id, excerpt,
published, published_at, sort_order, and a FULLTEXT index
- migration ALTERs guarded with IF NOT EXISTS for existing databases
- seed reworked into 4 sections with the 8 starter pages assigned
Security:
- new utils/sanitizeHtml.js (sanitize-html allowlist); wiki bodies are
sanitized on every save, and the article renders through DOMPurify
- strips <script>, event handlers (onerror), and javascript: URLs
Backend:
- public: published-only list with ?category filter + /wiki/categories
- admin: extended page CRUD, PATCH publish toggle, category CRUD;
drafts visible to admin, hidden from public
- all writes logged to activity_log
Frontend:
- data-driven public wiki index (sections + real descriptions; removed
hardcoded blurbs/Roman numerals) with ?category filtering
- article: category breadcrumb + sanitized render
- admin: Section/Status columns, draft/publish + section + excerpt in the
editor, and a Manage sections modal
Verified end-to-end against MariaDB 11: migration clean, XSS neutralized,
drafts hidden, client builds, server boots.
