Fix mobile terminal scrolling and session tool access

[bifrost0x]

Summary

• scroll normal xterm history directly from vertical touch gestures instead of relying on a synthetic wheel event that cannot trigger native browser scrolling
• preserve coordinate-aware wheel forwarding for tmux, Vim, and other alternate-screen or mouse-tracking applications
• replace the phone dock's global shortcuts with direct active-session destinations: Terminal, SFTP, Commands, Metrics, and More
• keep Hosts, the global File Manager, the Command Library, Notes, and all secondary actions available from More
• synchronize dock selection and disabled states with the active workspace and live SFTP/diagnostics capability
• bump all affected asset versions so mobile browsers do not retain the old behavior

Root cause

The previous touch bridge dispatched a synthetic WheelEvent. xterm uses native viewport scrolling for normal-buffer history, but browser default scrolling is not performed for script-dispatched wheel events. The event therefore existed and the unit test passed, while the terminal viewport did not move on a phone.

The original phone dock prioritized global destinations even though active-session SFTP, commands, and metrics are the frequent terminal-adjacent actions. Those tools required opening More, choosing a generic Tools action, and then selecting another tab. The revised dock puts the session workflow in the persistent thumb zone while retaining every global destination in More.

Validation

• 34 JavaScript test files passed
• JavaScript lint passed
• 59 focused Python UI and asset-version tests passed
• the 360 px Playwright workspace scenario passed after filling real xterm scrollback, performing a touch gesture, and verifying that viewportY moved away from the bottom
• the same browser scenario directly opened SFTP, Metrics, Commands, Terminal, and More from the revised dock and verified that global destinations remain available
• visual QA passed at 360 x 640 with the active session tool clearly highlighted in the persistent bottom dock
• git diff --check passed
