feat: swapcli commands to manually claim/refund and for database functions

new functions:

   claim                    manually call claim() in the contract for a given swap. WARNING: This should only be used if the normal swap process fails.
   refund                   manually call refund() in the contract for a given swap. WARNING: This should only be used if the normal swap process fails.
   get-contract-swap-info   Get information about a swap needed to call the contract functions. Returns the contract address, the swap's struct as represented in the contract, and the hash of the swap's struct, which is used as its contract identifier. Note: this is only useful if you plan to manually call the contract functions.
   get-swap-secret          Get the secret for a swap. WARNING: do NOT share this secret with anyone. Doing so may result in a loss of funds. You should not use this function unless you are sure of what you're doing. This function is only useful if you plan to try to manually recover funds.

I'm wondering if these should be gated under an "unsafe" or "dev" command/feature, since they shouldn't be used under normal circumstances, especially the manual claim/refund functions.
