remove dead Scrollable plumbing from TerminalView

TerminalView's build tree doesn't wrap content in a Scrollable —
scroll is handled by translating PointerScrollEvent into PgUp/PgDown
keyInput. The ScrollController parameter, _scrollableKey, internal
_scrollController, _scrollToBottom helper, and its five call sites
were all dead: _scrollableKey.currentState was always null because no
Scrollable in the tree carried the key, so _scrollToBottom's jumpTo
never fired.

Drops:
- public scrollController parameter on TerminalView
- _scrollableKey + _scrollController fields
- the didUpdateWidget swap block and dispose call
- _scrollToBottom + the five call sites
- KeyboardVisibilty wrapper (its only callback was _scrollToBottom,
  now a no-op; the widget remains a reusable primitive under ui/ for
  future use)
- the matching tests in terminal_view_test.dart

Same shape as T-93 (dead onTapUp wiring) and T-95 (dead tertiary tap
surface) — public API that no caller used + internal state that no
path executed.
