Replace read-only Settings with structured config editor

Settings view now has editable form controls organized by section:

Model: editable model name field, provider dropdown picker
Display: personality picker (parsed from config), streaming/reasoning/verbose toggles
Terminal: backend picker (local/docker/singularity/modal/daytona/ssh), max turns stepper
Voice: auto TTS toggle, silence threshold stepper
Memory: enabled toggle, char limit steppers, nudge interval stepper

All changes write via `hermes config set key value` CLI with save
confirmation feedback. Open in Editor button launches the raw YAML
in the default text editor. Paths and raw config sections retained.
