Align with Agave 4.3 and handle v1 transactions

[ArthurPaivaT]

• Aligns cloudbreak with Agave 4.3 and adds v1 transaction handling to simulateTransaction.
• Pins the solana crates at 4.3.0-beta.2 to match the Yellowstone gRPC tag the indexer runs.
• simulateTransaction now accepts v1 transactions, which can be larger than the 1232-byte legacy packet.

Dependencies (workspace)

• Solana crates moved to 4.3.0-beta.2. Yellowstone gRPC moved to the v16.0.0-rc3 tag for solana 4.3.0-beta.2.
• Three new crates: solana-runtime-transaction, solana-fee, solana-packet.

Simulate transaction (crates/api)

• Fee and budget rebuilt on TransactionConfiguration and calculate_fee_details, replacing the removed 4.2 helpers.
• decode_transaction detects v1 base64 input and applies per-version size bounds.
• New result arm for the NoOp processed-transaction case.
• The nonce path uses the SVMMessage and SVMStaticMessage trait methods, so the build has no deprecation warnings.

Indexer and snapshot (crates/index, crates/snapshot)

• Unknown slot status values now log and skip instead of panicking, matching the 4.3 proto.
• Added the new proto fields cuckoo_account_include and bank_id.

Config and database

• None. No config keys and no migration.
