refactor: move project to foundry template and introduce tests

This commit does a couple of things:

- moves the project to our foundry template structure and workflows
- removes hardhat usage and dependencies
- removes unused contracts
- ports existing JS tests to foundry tests
- adds additional tests for `CommunityERC20` contract
- Introduces deploy scripts written in solidity which are also covered
  by tests

The projects can now be build and tests with:

```
$ forge build
```

```
$ forge test
```

Test deployments can be done via

```
$ forge script script/DeployOwnerToken.sol
```

-# Sample Hardhat Project
+# Communities Contracts [![Github Actions][gha-badge]][gha] [![Foundry][foundry-badge]][foundry]
 
-This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.
+[gha]: https://github.com/status-im/communities-contracts/actions
+[gha-badge]: https://github.com/status-im/communities-contracts/actions/workflows/ci.yml/badge.svg
+[foundry]: https://getfoundry.sh/
+[foundry-badge]: https://img.shields.io/badge/Built%20with-Foundry-FFDB1C.svg
 
-Try running some of the following tasks:
+## Usage
 
-```shell
-npx hardhat help
-npx hardhat test
-REPORT_GAS=true npx hardhat test
-npx hardhat node
-npx hardhat run scripts/deploy.ts
+This is a list of the most frequently needed commands.
+
+### Build

+Delete the build artifacts and cache directories:
+
+```sh
+$ forge clean
+```
+
+### Compile
+
+Compile the contracts:
+
+```sh
+$ forge build
+```
+
+### Coverage
+
+Get a test coverage report:
+
+```sh
+$ forge coverage
+```
+
+### Deploy
+
+Deploy to Anvil:
+
+```sh
+$ forge script script/DeployOwnerToken.s.sol --broadcast --fork-url http://localhost:8545
+```
+
+For this script to work, you need to have a `MNEMONIC` environment variable set to a valid
+[BIP39 mnemonic](https://iancoleman.io/bip39/).
+
+For instructions on how to deploy to a testnet or mainnet, check out the
+[Solidity Scripting](https://book.getfoundry.sh/tutorials/solidity-scripting.html) tutorial.
