Archive projects, auto-add default members, rebuild the admin console

Three things asked for together, plus the migration they share (a7c31f9e5b02 —
additive, with database defaults for existing rows, so unlike the users.role
rewrite it is safe under a code-only rollback).

ARCHIVE A PROJECT. A finished job leaves every picker, switcher and search, and
freezes read-only, without losing anything. Hiding is free: GET /api/projects
defaults to archived=exclude, so the home picker and the app-bar switcher drop it
without either of them changing. Freezing is require_project_writable(), which
every write that lands on a project now goes through — SOP and WP upserts (both
ends, so a package can be moved neither into nor out of an archived job), deletes,
issue, status, WP archive, and comments on its WPs/SOPs. It answers 409, not 403:
nobody lacks a permission, the project's state is the objection, and the browser
outbox in project-data.js retires 4xx ops instead of retrying them against a job
that will never accept them. Unarchive and delete stay allowed on purpose —
unarchive is the one write an archived project must take, and archive-then-delete
is a normal sequence.

DEFAULT MEMBERS ON NEW PROJECTS. users.auto_add_projects / auto_add_role flag the
people who belong on every job, so an admin says it once instead of remembering it
at each project creation. It runs on the is_new branch of upsert_project, which is
the single road into project creation, so the home page, the sample project and the
demo seeder are all covered and an update never re-runs it. Note the interaction
with the existing creator-grant: that row commits first and add_default_members
never overwrites an existing membership, so the creator grant now carries the
creator's own auto_add_role — otherwise someone flagged "Project Admin on every
job" would land as a plain member on the one job they started themselves.

ADMIN CONSOLE. The user table had outgrown .wrap{max-width:860px}: nine columns in
an 860px card meant every cell wrapped, so one user occupied a ~100px band, the
action buttons stacked, and the table spilled outside its own white card. Now
1240px, with wide tables scrolling inside .tscroll so the page itself never scrolls
sideways, and one spacing/control scale across all twelve cards. Truncation hangs
off a span inside the cell rather than max-width on the td, which table-layout:auto
treats as advisory — the usual reason cell ellipsis works in the stylesheet and not
on the page.

Found in review and fixed here rather than later:

- Stored XSS in the new Projects card, reachable by any signed-in user, landing in
  an admin's session. The uesc(v).replace(/'/g,"\'") idiom this file already used
  in eight places escapes in the wrong order — uesc leaves backslashes alone, so a
  stored name containing \' closes the JS string literal and the rest executes.
  jsq() does backslash, then quote, then HTML, and all thirteen handler bindings go
  through it. The same bug, unescaped entirely, was in the SOP builder's custom
  constraint names (escHandlerArg there). Three of seven test payloads escaped the
  literal under the old idiom — one of them a plain name ending in a backslash, so
  it was breaking buttons for innocent input too.
- _save_comment resolved wp_id and sop_id with if/elif but stored both, so a
  payload naming a WP you may touch and a SOP you may not was authorised on the WP
  alone and still wrote into the other project's thread. Both are checked now.
- Promoting an account to admin left its default-member flag set but invisible,
  ready to take effect again on demotion — cleared, as set_user_auto_add already
  does for the role.

smoketest.py and the console's own smoke test both assert the archive round trip:
out of the default list, present with archived=all, writes refused with 409, and
all of it undone by unarchiving.
