Fix Anchor and Quasar CI failures

- Fix default-account-state quasar: revert InitializeMint2 to 67 bytes
  (1-byte COption flag, not 4-byte LE u32) and correct mint_size to 171
  (165 base + 1 account_type + 4 TLV header + 1 extension data)
- Fix transfer-fee anchor: handle_check_mint_data takes &Initialize not
  &mut Initialize since it only reads data
- Fix CPI anchor test: use CARGO_MANIFEST_DIR for absolute path to
  lever.so instead of relative path from package root
- Add tokens/spl-token-minter/quasar to .ghaignore (no Quasar.toml)
