feat(trust): let users add trusted folders from settings (#1812)

* feat(trust): let users add trusted folders from settings

The trusted-locations check already matches projects by path prefix, but
the only way to populate it was the "Trust projects in…" checkbox on the
first-open dialog — a folder could never be trusted ahead of time.

Add a project_trust_add_location command that canonicalizes the picked
directory, rejects non-directories, and deduplicates, plus an "Add
folder…" button on the Project Trust settings page backed by the native
directory picker.

Fixes #1743

* fix(trust): translate the trusted-location additions into Chinese

The zh source-text catalog must cover every literal UI text; the three
new strings in the trusted-locations settings page were missing.
