test: Fix Group 9 Feature & Interface Tests for DigiByte v8.26

Fixed 12 tests in Group 9 (Feature & Interface Tests):

1. feature_shutdown.py - Already working (no changes needed)
2. feature_startupnotify.py - Already working (no changes needed)
3. feature_unsupported_utxo_db.py - Updated block reward from 50 to 72000 DGB
4. feature_utxo_set_hash.py - Updated to DigiByte-specific hash values
5. feature_versionbits_warning.py - Already working (no changes needed)
6. interface_rest.py - Fixed Dandelion++, fees, wallet bypass, and sync issues
7. interface_usdt_utxocache.py - Updated block reward from 50 to 72000 DGB
8. interface_usdt_utxocache.py --descriptors - Added missing add_options method
9. mempool_unbroadcast.py - Added error handling for Dandelion++ rebroadcast behavior
10. mining_basic.py - Fixed timing, wallet deps, version bits, and error codes
11. mining_prioritisetransaction.py - Updated fee calculations for DigiByte
12. rpc_validateaddress.py - Updated error messages for DigiByte's simplified validation

Application bugs fixed:
- REST API compatibility with Dandelion++ and fee requirements
- Mining test compatibility with 15-second blocks and multi-algo
- Transaction prioritization with DigiByte's fee structure
- Address validation error reporting differences
