docs(asset-leasing): drop 'SPL Token' qualifier, just say 'token'

Tokens are the default on Solana; no need to qualify with 'SPL'. Reserve
'SPL Token' for the rare case of contrasting with the native token (SOL).

- README account table: 'SPL Token' -> 'token account' (matches what the
  column actually describes: an ATA, not a token type)
- README prose: '6-decimal SPL tokens' -> '6-decimal tokens', 'same SPL
  mint' -> 'same mint'
- Cargo.toml description: 'Fixed-term SPL token leasing' -> 'Fixed-term
  token leasing'

Left SPL_TOKEN_PROGRAM_ID identifiers alone -- those are program IDs,
not prose.
