Adds `@types/lodash.camelcase` to `twenty-shared`. **Why:** `lodash.camelcase` has no bundled types. Those types used to come from the root `devDependencies`; after scoped/hoisted deps (#20140), they are no longer guaranteed in the Docker `common-deps` graph, so `twenty-shared:build` (pulled in before server Lingui) fails with TS7016. Declaring the types on the package that imports `lodash.camelcase` fixes CD. Co-authored-by: Cursor <cursoragent@cursor.com>
