Merge release v3.0.6 (#2290)

This firmware update adds support for Solana's new V1 transaction format and changes how oversized or malformed transaction details are displayed. The code introduces a dedicated parser for V1 messages with strict size and structure checks…

New parser enforces hard limits on V1 message fields and rejects malformed 0x81-prefix payloads instead of falling back to message signingCompute-budget instructions in V1 are explicitly ignored to prevent fee-display spoofingUI pagination change for large transaction details reduces truncation risk
