Text-Editor: V-Align + Mask-Type/Color + Case-Transform

Erweitert den Editor um die fehlenden Rhino-Text-Optionen:

- Vertical Alignment (Top/Middle/Bottom) als 3 Pill-Buttons in Row 2.
  Backend: text_create._apply_valign mit TextVerticalAlignment-Enum.
- Mask-Type Dropdown (None/Viewport/Solid). Bei Solid erscheint ein
  Mask-Color-Picker. MaskMargin disabled wenn Type=none.
  Backend: schaltet te.MaskEnabled + te.MaskUsesViewportColor +
  te.MaskColor entsprechend.
- Case-Dropdown in Row 2: upper/lower/capitalize/invert. Wirkt nur
  auf die Selektion via execCommand insertText.

open_for_edit liest valign + maskType/Color/Margin aus bestehendem
TextEntity zurueck, damit beim Re-Open der Zustand erhalten bleibt.
