gnd: Fix mapping file path and kebab-case conversion in scaffold

- Add ./src/ prefix to mapping file path in generated manifest (I7)
  The manifest referenced ./simple-contract.ts but the file was
  created at ./src/simple-contract.ts
- Replace buggy custom to_kebab_case with Inflector (A3)
  Custom implementation incorrectly converted ERC20 -> e-r-c20
  Inflector correctly produces erc20 (keeps acronyms together)
