Hono's `html` tagged template auto-escapes all interpolated values;
`raw()` is used for the email body which must render as HTML.
This removes the ad-hoc utility and aligns entries.ts with the
same pattern already used in admin.ts.

- Make feedId required in generateRssFeed (removes dead /emails/ fallback)
- Hoist loop-invariant conditional and remove intermediate variable
- Extract normalizeAllowedSenders() so JSON and form paths share same logic
- Move escapeHtml to src/utils/html.ts for reuse by admin.ts
- Parallelize the two independent KV puts in feed creation

Serves each email as a standalone HTML page with a Content-Security-Policy
header, useful for reading emails outside a feed reader and for debugging.
Also updates RSS item links to point to this route.
