Add Project Home, Auth Bridge, shared auth token, and Tier-1 polish

Project Home (DESIGN-REVIEW §B2): the project is promoted from a 280px
sidebar card to a first-class main-area view. ProjectCard.tsx (1,257
lines) is replaced by a select-only ProjectRow plus tabs for Overview,
Sessions, Automation, Config and Files. The PortMappings, FileManager
and ContainerProgress modals are absorbed rather than reimplemented.
Config gains a Saved/Saving/Failed indicator — save-on-blur failures
previously reached only console.error.

Tier-1 polish (DESIGN-REVIEW §A): new elevation, muted-accent, disabled
and focus-ring tokens; a global :focus-visible ring with every
focus:outline-none removed; filled buttons moved to --accent-emphasis
and white-on-success toggles retired, fixing three WCAG AA failures
(2.1:1, 2.5:1, 2.4:1); a shared Modal primitive with role="dialog",
focus trap and restore, adopted by all remaining modals; status
indicators that carry a glyph and word rather than colour alone.

Ctrl+Shift+W closes a tab, deliberately not Ctrl+W — that is readline's
kill-word, used constantly in the terminal this app is built around.

Auth Bridge: a general loopback-callback bridge so browser logins run
inside a container (aws sso login, Concourse fly login, claude login)
can complete against the host browser. Listeners are discovered from
/proc/net/tcp{,6} — ss/netstat/lsof are absent from the image — bound on
host 127.0.0.1 only, and tunnelled in over the Docker API via socat,
which keeps working on Docker Desktop where container IPs are not
routable. Falls back to [::1] because Node resolves localhost to IPv6
first, so claude login often binds ::1 alone. Opt-in per project.

This extracts create_attached_exec() and moves the existing terminal
session path onto it, so there is one attached-exec implementation
rather than two.

Shared auth token: `claude setup-token` is run in a container, the token
is stored in the OS keychain and injected as CLAUDE_CODE_OAUTH_TOKEN
into Anthropic-backend projects. Contrary to the initial design note,
setup-token uses an Anthropic-hosted redirect and blocks on a stdin
paste prompt rather than a loopback callback, so a stdin command is
required for the flow to complete.

The token is never logged, never returned to the frontend, and is
redacted from the streamed output with a stateful matcher that withholds
any tail that could still grow into a secret. Change detection uses a
random rotation id rather than a hash, since a hash in a docker-inspect
readable label would be an offline verification oracle.

Frontend 33 -> 51 tests; Rust 34 tests. Both builds clean.
