Email library chip-bar: smaller pills, persist across refresh, Esc + sender click

Four fixes from the first round of usage:

1. Pill height was larger than the chip-bar's row — shrink to a fixed
   18px-tall pill (line-height + height pinned) so it sits inside
   the input row.

2. List refresh wiped pill state — when _loadEmails replaces
   state._libEmails (refresh, folder switch, etc.), refresh the
   snapshot to the new list and re-apply the pill filter so pills
   persist instead of resetting to 'show all emails'.

3. Click-to-add only worked inside the open email reader. Extend the
   capture-phase handler to ALSO catch clicks on .email-meta-sender
   inside the library grid — the list card's sender name is the most
   natural place to want to pivot from.

4. Esc inside the chip-input didn't close the modal. New behaviour:
   if the autocomplete dropdown is open, Esc closes only the dropdown
   (and swallows the event); otherwise Esc blurs the input and bubbles
   so the existing modal Esc handler can close the library.

Also wires data-email + data-name on .email-meta-sender so the click
handler has reliable targeting.
