fix: add requires_firmware("7.14.0") gates to all new chain tests

CI emulator is v7.10.0 — new 7.14.0 tests (EVM clear-signing,
Solana, TRON, TON, Zcash Orchard, Zcash PCZT, Zcash v5) fail with
"Unknown message" or missing client methods. Adding version gates
so they skip gracefully on pre-7.14.0 firmware.

24 failures → 24 skips on the old emulator.
