Replace the Markdown composer with a small contenteditable WYSIWYG (Codex
greenlit for this narrow, admin-only surface).
* markup.py: render_reply_html → sanitize_reply_html + reply_html_to_text.
Allowlist rebuild via stdlib HTMLParser — keeps strong/em/p/br/ul/ol/li and
span ONLY with a whitelisted font-size (13/15/18/22px); normalizes b→strong,
i→em, div→p, <font size> → safe span; drops links/images/arbitrary styles
(content kept as escaped text) and discards script/style content entirely.
* API: FeedbackReplyBody.html (raw editor HTML); endpoint sanitizes → message_html,
derives plain text → stored message + the email text/plain part. Unchanged:
multipart send, store-on-success, conn released during SMTP, mark-read, 404/400/422.
* Frontend: contenteditable editor + toolbar (Bold/Italic/Size/• List/1. List),
execCommand with styleWithCSS=false for semantic tags, font size wraps the
selection in a fixed-px span, paste intercepted as plain text. No links yet.
