fix(tui): G jumps to last log; Agents ←/→ switch panes

The global "switch to Settings" shortcut matched both g and G, so
uppercase G never reached the logs panel and the vim-style "jump to
end" never fired. Restrict the global handler to lowercase g; G
falls through to the active panel — including the status-mode logs
list (jump-to-newest) and any other scrollable panel that opts in.

Agents view: ← focuses the list pane, → focuses the detail pane,
matching the visual layout. Tab still cycles either direction.
