Basic form

[hpmaxi]

Closes #2

Some improvements for another pull request, and with more time, given that opportunity, this should be validated and prioritized.

• [ ] hardhat action prints an Id, maybe here we can show a modal with the same information about the tx.
• [x] Move easyAuction address to env variable and build an object with networkIds as keys to get the correct address for the network of the current safe.
• [x] Extract initiateNewAuction and easyAuction to a hook that compose with useSafeAppsSDK.
• [ ] Split responsibility of initiateNewAuction to validate balances and allowance beforehand.
• [x] Don't be able to submit the form without everything valid, an effect with formState.errors should do it but the Controller with rules isn't working. There is a regular expression for addresses, and also some helpers from react-hook-form to validate numbers. More details are needed or I could read which guards are in the contracts.
• [x] Use logo and name in manifest.json, and a favicon too.
• [ ] Add a button to use all balance available?
• [ ] cancel submission could be more useful.
• [x] At hover we can show descriptions of each field as are in the hardhat action
• [ ] An endAdornment with a symbol of the selected ERC20
• [x] Add option to edit the others parameters, a group of hidden inputs behind an advanced options text, or something like that
• [x] Deploy it somewhere.

I marked 3 points that I think are the most relevant for us and the basic user experience
