fix(shell): set database on initial load COMPASS-9204

COMPASS-9204

Previously we wouldn't use the database the user's collection it in when they click the shell button. It would only use the database after the first time the shell was rendered. This ensures we use the intended database.

Added a regression e2e test.

Pull request overview

Fixes COMPASS-9204 by ensuring the Shell tab applies the intended database context on first open (from a collection) by deferring the “initial eval applied” state until mongoshVersion is known, and adds an e2e regression test that opens the shell from the collection header.

Changes:

• Gate initial-eval “applied” state on mongoshVersion so the first Shell render can correctly apply the use <db> initial eval.
• Add e2e coverage for opening Shell from a collection header and verifying db/collection context.
• Refactor e2e shell commands to distinguish opening Shell from the sidebar vs. from a collection header.
