#191: feeds.enabled instance switch, feed-token log masking
Chosen path: an instance master switch following the api.enabled/
mcp.enabled pattern — while off, both feed routes AND the feed-token
management answer 404 (existence hidden). Default ON: feeds predate the
switch, existing instances and their subscribed readers keep working;
the VS-NfD reference configuration (#227) turns it off. Admin UI gets
the toggle next to the API/MCP switches (i18n de+en).

Moving the token out of the query string is documented as rejected: a
path segment lands in the same proxy and request logs, and feed readers
cannot send headers — that is why the credential is in the URL at all.
What DID leak was our own request log (pino logs req.url): the req
serializer now masks ?token= values (common/mask-token-param.ts), so no
code path logs the credential.
