jcoffey 23557a72a2 Quote images through the proxy, and unproxy them on the way out (#412) (#413)
Reading a message fetches its remote images through this server, so the
sender learns nothing about the reader. Quoting the same message into a
reply fetched them directly: same pixel, same reader, but the request
carried their IP and user agent -- exactly what the proxy withholds.

A quote now proxies them the way the message view does. That alone would
be wrong, because a proxied URL belongs to this deployment: sent
unchanged it would reach the recipient as images only this server can
serve, broken for them and a beacon back here. So buildEmailObject turns
them back into the addresses they came from, beside the pass that
restores images blocked under pr411 and the one that turns editor blob
URLs into cid: references.

Deployments with the proxy off are unaffected: the quote fetches
directly, as reading does there.

Three tests from pr411 asserted the address sat in src when images were
allowed, which was the old behaviour; they now ask whether the draft
fetches it at all, proxied or not.

No new strings.

jcoffey-dev 55fcbf72f5 Harden the email sanitizer's CSS handling
Rewrite mail CSS in place instead of cutting pieces out, so a strip can no
longer join text into a closing </style>, and escape < last. Decode escaped
letters before checking, parse url() properly and drop CSS that cannot be
parsed, and disable @import and image-set() in every spelling. The body
element's style goes through the same path.

Give <area> links the same target, rel and click handling as <a>, strip
<style> blocks from HTML quoted into the composer, and contain the editor's
layout as .message-body already is.

jcoffey-dev bd6a605d61 Group six more clusters out of web/src/lib
Takes the flat module count from 66 to 42, continuing what admin/ and
calendar/ started.

  lib/mailbox/  archiveDate, emptyFolder, folderMove, labelTree,
                mailboxName, mailboxRoute
  lib/sieve/    sieve, sieveApply, sieveFolders
  lib/input/    keyboard, swipe, touch, listSelection, dropUpload
  lib/notify/   notify, webpush, webpushEnable
  lib/sw/       swCache, swFacts, staleBuild
  lib/text/     html, markdown, text, emlName

FOUR THINGS THE FILENAMES GET WRONG, each checked by reading the file
rather than trusting what it is called:

  - appFolder is not a mailbox. It is the `ihasmail` folder in JMAP
    *Files*, where the client keeps signature images and synced settings.
    It stays flat.
  - format holds no formatting of text. It re-exports the date and clock
    formatters, so it belongs with dates/datetime, not with text/.
  - preview is the file viewer deciding what it can show without
    downloading, and source is where to point someone asking for this
    instance's AGPL source. Neither is about text.
  - notify is not Web Push. It is the tab title, the favicon badge and
    the new-mail sound -- in-app notification, which is why it sits with
    webpush rather than under sw/ with the service worker's own concerns.

threadScroll stays flat too: it decides where a conversation opens, which
is view state rather than a gesture, and input/ is honest only if
everything in it interprets something the reader did.

No behavior change. Almost every reference was on the @/ alias; eight
relative imports in files that did not move, or that moved away from a
sibling, needed rewriting by hand.
