settings: qtmaildir's config, in four Mail pages

qtmaildir is configured through qtmaildir.conf alone, which it reads at
startup and never writes. Four settings pages under a new Mail group
edit it: Mail ([general], [sync], [completion]), Compose, Accounts (a
card per account, add and remove) and Tags & shortcuts ([tagcolors] and
[keys]). Fields save on Enter and unset when emptied, with qtmaildir's
defaults as placeholders and numbers range-checked; the pages say when
qtmaildir is running and a change waits for its restart.

Ini.js edits the file line by line so its comments survive. Headers are
only whole [name] lines: a section is never cut at the next "[", since
values such as [Gmail]/Bozze hold brackets, the trap AGENTS.md records.

The shortcut actions are copied from qtmaildir's KeyMap::knownActions()
rather than exported by it, since a CLI flag there would have meant
translations and a changelog entry; the field also takes free text, and
the copy is marked as a ponytail ceiling.

The settings sidebar now clips, which a list long enough to scroll
showed it did not: entries drew over the search box.
