V202 - V195 safe base

Changes only:
- DELETE ACCOUNT button disabled.
- Native Import UI hides the four stock/pregenerated CHR entries: OH1FIGHT (Abdel), OH2MAGE (Daria), OH3THIEF (Lessa), OH4CLER (Rothgar).
- Import selection keeps a source-index map so account character rows still select the correct native BG2 entry.
- No automatic character backups/restoration added.
