Replaces the abandoned monarchmoney (hammem) with the actively maintained
monarchmoneycommunity fork (bradleyseanf). This resolves the API domain
migration issue where api.monarchmoney.com 301-redirects to api.monarch.com,
causing Authorization header stripping and 401 errors.
- Update dependency: monarchmoney>=0.1.15 -> monarchmoneycommunity>=1.3.2
- Update gql pin: >=3.4,<4.0 -> >=4.0,<5.0 (required by community fork)
- Remove runtime BASE_URL patch (no longer needed, fork has correct URL)
