feat: direct TCP URI with SSL toggle and optional password auth (#635)

* feat: direct TCP URI with SSL toggle and optional password auth

Replaces the heuristic-driven direct-connection model with a user-controlled
one. The Add Host dialog now exposes structured Host, Port, "Use SSL", and
masked Password fields that compose the canonical
`tcp://host:port?ssl=true&password=xxx` URI used as the storage form.

The daemon gains optional shared-secret auth: `Authorization: Bearer <pw>` on
HTTP and `Sec-WebSocket-Protocol: paseo.bearer.<pw>` on the WS upgrade
(browser WebSocket can't set custom headers). Configured via config.json
`auth.password` or `PASEO_PASSWORD` env. Off by default — old clients keep
working unchanged.

The `port === 443` heuristic for ws/wss is gone; the explicit `useTls` flag
drives scheme selection at every call site.

* fix: stabilize direct tcp auth ci checks

* fix: restore fetch stub in bootstrap smoke test

* fix(app): collapse Advanced section in add-host modal

* feat(server): hash daemon password in config

* fix: update lockfile signatures and Nix hash

* Improve direct TCP auth failures

* Fix workspace cwd updates after rebase
