feat: `dry-run` flag to estimate gas

[AlexD10S]

For pop up contract and pop call contract adds a new flag --dry-run to perform a dry-run via RPC to estimate the gas usage without submitting a transaction.

Closes https://github.com/r0gue-io/pop-cli/issues/134

This PR also corrects some inaccurate error messages and refactors these errors to use the thiserror crate in the pop_contracts module. This refactor continues the work initiated in the previous PR: https://github.com/r0gue-io/pop-cli/pull/111 Integration tests are required to test the call and up contracts, but is our of scope of this PR.
