Some fixes for xeddsa pr (#9610 )

* fix: add null check for getMeshNode() in NodeInfoModule getMeshNode() can return nullptr for unknown nodes. Dereferencing without a check crashes the firmware when receiving NodeInfo from a node not yet in the database. * fix: enforce XEdDSA signature verification and prevent stripping Previously, failed signature verification still allowed the packet through, making signatures purely cosmetic. Now: - Failed verification drops the packet (DECODE_FAILURE) - Successfully verified nodes get HAS_XEDDSA_SIGNED bitfield set - Unsigned packets from previously-signing nodes are rejected - Log levels reduced from WARN/ERROR to DEBUG/WARN as appropriate * fix: include packet metadata in XEdDSA signature The signature now covers [fromNode | packetId | portnum | payload] instead of just the payload bytes. This prevents: - Replay attacks (different packetId fails verification) - Reattribution (different fromNode fails verification) - Portnum redirection (different portnum fails verification) Also adds a key initialization check to xeddsa_sign (returns false if XEdDSA keys are all zeros) and checks the return value in the encode path. * fix: handle existing key pair in AdminModule security config When a user provides both a valid private key and public key via admin config, the crypto engine's DH private key and owner public key were never loaded. DMs and XEdDSA signing would silently break. Add an else branch to load both keys into the crypto engine. * perf: cache Ed25519 public key conversion in xeddsa_verify curve_to_ed_pub() performs field element parsing, inversion, and multiplication on every call. Since packets from the same node tend to arrive in bursts, a single-entry cache avoids repeating this expensive conversion for consecutive packets from one sender. * fix: skip identity cleanup when node number is unchanged createNewIdentity() was called on every generateCryptoKeyPair(), including normal boots where the same key is regenerated. This caused unnecessary NodeDB writes and old-node cleanup logic to run when the node number hadn't actually changed. Also fixes only zeroing byte[0] of the old node's public key instead of clearing the entire array. * fix: replace hardcoded 120 with derived XEDDSA_SIGNATURE_SIZE constant The payload size check for XEdDSA signing used a magic number (120). Replace with a derivation from DATA_PAYLOAD_LEN and XEDDSA_SIGNATURE_SIZE so the limit adjusts automatically if constants change. This also increases the max signable payload from 120 to 169 bytes, which is still safe since the actual encoded size is checked after pb_encode. * fix: add const qualifiers to XEdDSA verify and curve_to_ed_pub inputs pubKey, payload, and signature parameters in xeddsa_verify are input-only and should not be modified. Same for curve_pubkey in curve_to_ed_pub. * chore: remove commented-out old Crypto dependency in portduino.ini * Leave out the admin module change for now --------- Co-authored-by: Jonathan Bennett <jbennett@incomsystems.biz>
