feat(mobile): start a session in a project from the sessions drawer

Project rows carried an active-project dot and a session count, neither of
which answers a question the user has while browsing the drawer, and there
was no way to start a session in a project's root directory: the only
per-row action was creating a worktree.

Drop both indicators and put a "+" beside the worktree button instead. It
opens a draft already carrying the project and its directory, the same
contract as the desktop sidebar's per-project "+", so the current
directory is not switched out from under the session behind the drawer.
Project rows in search results lose the count the same way and gain the
same button; dropping it there also drops a per-project session scan that
ran on every keystroke.

Testing: package type-check and lint; drove the mobile surface in a
browser against an isolated server (rows render the button, counts gone).
