fix: replace user-facing hardcoded ~/.hermes paths with display_hermes_home()

Prep for profiles: user-facing messages now use display_hermes_home() so
diagnostic output shows the correct path for each profile.

New helper: display_hermes_home() in hermes_constants.py
12 files swept, ~30 user-facing string replacements.
Includes dynamic TTS schema description.
