fix(tui): clean pseudo-version in footer, rename Sites tab to Monitors

Strip Go module pseudo-version suffix (timestamp+hash+dirty) from the
footer version string — shows "v0.1.0" instead of the full build
metadata. Rename "Sites" tab and breadcrumbs to "Monitors" for
consistency with README, CLI help, and user-facing docs.
