Fix MLIQ water parsing, skip interior water, clear movement on teleport

- Remove bogus 2-byte skip after materialId in MLIQ parser that shifted
  all vertex heights and tile flags by 2 bytes (garbage data)
- Skip liquid loading for interior WMO groups (flag 0x2000) to prevent
  indoor water from rendering as outdoor canal water
- Clear movement inputs on teleport/portal to prevent auto-running after
  zone transfer (held keys persist through loading screen)
