feat: implement delete account functionality

[Adebisi1234]

I've implemented delete account route
Also written test for the route

I couldn't test the code locally because I couldn't get the container running with postgres

I'll appreciate your review of the code and testing.

closes #366

@Adebisi1234 can you resolve the failing tests

you can install ganache and run a local blockchain with HD_WALLET_MNEMONIC="media nerve fog identify typical physical aspect doll bar fossil frost because"; ganache -m "$HD_WALLET_MNEMONIC" --chain.chainId 1337 -l 21000000

then run the tests with go tests -v ./...

@chibie thanks I've been able to resolve all failing test.

Couldn't run the test cases previously because spinning up the docker image keeps failing while connecting to postgres

@chibie are there still some changes I need to implement? Or why is the pr not being merged

The failing test case isn't from my implementation
