Fix iOS native keyboard dictation in mobile terminal inputs

iOS terminates an active keyboard-dictation (and IME) session whenever
JS writes text into the focused field that differs from the native text.
Both terminal inputs echoed normalized text back into their controlled
value, so smart-dash rewrites and dictation hypothesis revisions
triggered native setTextAndSelection writes that killed dictation.

Store the raw field text in the controlled value and apply dash
normalization only on the PTY mirror / send path, which already
normalizes. Refs stablyai/orca#7925.
