fix: web speech STT repeating previous transcriptions and inserting text on cancel (#26793)

Browse source 
The VoiceRecording component stays mounted (hidden) between recordings, and the web speech engine accumulated every session's transcript into the never-reset transcription variable. Each new recording therefore confirmed all previous utterances again, so the inserted text repeated once per session and previously deleted text reappeared in the input.

Additionally, cancelling a recording (X button, Escape or a recognition error) called stopRecording(), which stops the SpeechRecognition instance and fires its onend handler, which unconditionally confirms the transcription. Cancelled recordings therefore still inserted the accumulated transcript.

Reset the transcription at the start of each web speech session and detach the onend handler on cancel so cancelled recordings no longer confirm.

Fixes #26784
