feat: logic for parachain registration

[AlexD10S]

This is the first step in a larger PR: PR #404. It consolidates the existing logic for deploying a parachain into a relay chain when a user executes pop up in a parachain project.

Changes included:

• Added generate_genesis_artifacts function in specs to build and return paths for the genesis and WASM files.
• Updated submit_extrinsic_with_wallet to return events.
• Parsed the Reserved event in the Registrar pallet to retrieve the parachain ID after reservation.
• Integrated the entire process: reserving the paraID, generating specifications, and registering the parachain in the pop up command.

How to test it
Start the Paseo parachain locally by running:

pop up parachain -f ./tests/networks/paseo.toml

Run pop up in your parachain folder or specify the folder with the path flag

pop up --path ../test-chain --relay-url ws://127.0.0.1:49155

Note: The account used for signing must have sufficient funds to cover both the reservation and signing process.

Notes:

• I tried to have a more generic event parsing approach but couldn't find a viable solution. Instead, I followed the approach used in cargo-contracts: Reference. If we need to parse more events in the future, we can manually add them.
• To sign this logic is using the wallet signing approach (--use-wallet). If useful, I can add options for --suri and specifying a private key via the command line, but not sure if makes sense.

Refactored the logic for generating the chain spec and raw chain spec into the generate_chain_spec function.

[AlexD10S]

This function is now reused in pop up, so it might make sense to move it to a common file. But I wasn’t sure about making additional changes.
