Release 1.9.0: Quick Jump copy-to-clipboard section (#23)

The uid_-_target grammar-mode SSH command was documented in the README but
nowhere in the UI itself -- users had to remember/reconstruct the format by
hand. Adds a "Quick Jump" card with a one-click-copy command for the
interactive-picker form, plus a copy button on every row of "Hosts you can
reach" that copies the exact grammar-mode command for that specific host
(using the logged-in user's own uid, so it's ready to paste and run as-is).

conf.ssh.listenPort is now passed to the dashboard view so the command can
include the right -p flag when the SSH front door isn't on the default port
22 (theta-env, for example, exposes it on 2222).

Verified live: logged in as the local admin user, confirmed the Quick Jump
command and a per-host command both populate correctly and copy to the
clipboard (toast confirmation), and that the per-host command matches the
exact uid_-_target grammar the SSH server's parseUsername expects.

+## [1.9.0] - 2026-07-28
+
+### Added
+- **"Quick Jump" copy-to-clipboard section on the dashboard** — the `uid_-_target` grammar-mode SSH command was documented in the README but nowhere in the UI. A new card gives a one-click-copy command for interactive-picker mode, and every row in "Hosts you can reach" has its own copy button for the exact grammar-mode command to that host, ready to paste and run as-is (uses the logged-in user's own uid).
+
+## [1.8.2] - 2026-07-28
+
+### Fixed
+- **Audit records for a failed upstream connection only ever said `upstream-unreachable`** — `resolveAndConnect` discarded the real error from `connectUpstream` (ECONNREFUSED, ETIMEDOUT, an ssh2 auth-failure message, etc.) and replaced it with that one generic string, so there was no way to tell a network-layer failure from an auth failure from the audit log alone. This is what blocked root-causing the "Could not reach 192.168.1.206" (emby host) report — the real error is now captured and surfaced as a new `failDetail` field on the audit record, shown as a tooltip on the fail badge in the admin audit table.
+
+## [1.8.1] - 2026-07-28
+
+### Fixed
+- **Redis had zero persistence** (`--save '' --appendonly no`, no data-dir volume) — every container rebuild/recreation silently wiped all sessions, in-flight OAuth logins, and any admin-created API token. This is why re-running `setup.sh` appeared to "break OAuth with jump": the jump-host container gets recreated, and any token or in-flight login vanished with it. Now Redis persists (AOF + periodic RDB) to `/data`, mounted as a named volume (`jump-redis-data`) in theta-env's compose file. Verified live: minted a PAT, force-recreated the container, confirmed the same PAT still authenticated afterward.
