v0.4.8: seven UX fixes for the BAL inheritance plugin

- #04: Raw/Date selector now reappears on the WILL/HEIR tabs when switching to
  ADVANCED (and when a raw value is pushed from the wizard), keeping the current
  value/editor. New BalTimeEditWidget.apply_user_type_visibility() wired into
  WillSettingsWidget for both the locktime and check-alive boxes.
- #3: Building Will report window minimum height 500 -> 450 px.
- #5: 'User Type' setting moved to the bottom, above 'Rebroadcast transactions'.
- #6: enabling ADVANCED now requires typing 'at My Risk' (case-insensitive);
  wrong phrase or cancel reverts to BASIC. QInputDialog added to common import.
- #7a: on CHECK with an emptied wallet, an extra reassuring line is shown on
  'Checking your will': 'Inheritance already executed (on blockchain)' in GREEN
  (CONFIRMED) or 'Inheritance in mempool (waiting confirmation)' in ORANGE
  (MEMPOOL). New _executed_inheritance_status() helper.
- #7b: 'Balance is too low, or CheckAlive is in the past. Skipped' (space added)
  recoloured to ORANGE instead of red.
- Reset button renamed 'Reset setting' -> 'Reset to Default Setting'.
- Added tests/test_group_h_v048.py (8 tests). Version 0.4.7 -> 0.4.8.
  Full suite: 266 passed; ruff clean; CHANGELOG #24; memory updated (#04 done).
