Session UX: inline password prompt and terminal font size controls

Replace the modal RDP/SSH password dialog with an inline prompt bar
embedded in the session tab instead of a separate popup window. Add
per-tab terminal font size controls (increase/decrease/reset/set
exact point size) via the tab context menu, with the chosen size
persisted across sessions.
