feat(feeds): site-scoped RSS add infers account, parser and poll

Adding a feed from a site page now only asks for the URL, purpose
(discover / track / promotion) and an optional note. POST /feed-sources
with siteId infers the site account (passkey holder first), records the
site definition version as parserVersion, defaults the name to
"<site> RSS" and polling to 30 minutes, and returns non-blocking
warnings when the URL host does not match the site. The dialog shows the
redacted URL, fetches once right after saving and reports the item count
or the error.

The generic feed form on the sources page suggests linking a registered
site when the URL host matches (can be undone). name is now optional.

Takes effect after the stack is rebuilt.
