Fix remaining Quasar CI failures

- Add 5 stub quasar dirs (no Quasar.toml) to .ghaignore:
  external-delegate-token-master, nft-minter, nft-operations,
  token-swap, and oracles/pyth (broken API)
- Fix interest-bearing mint_size: 234→222 (165+1+4+52 for InterestBearingConfig)
- Fix mint-close-authority mint_size: 218→202 (165+1+4+32 for MintCloseAuthority)
- Fix metadata test: encode instruction data as fixed-size padded arrays to
  match function signature ([u8; MAX_NAME] + u8 len, etc.)
