feat(functions): add remaining functions routes (#117)
* feat(/functions): add remaining functions routes functions list action is already implemented, adding the remaining actions (get, post, patch, delete). Beginning with this test for GET on /functions/:id * Adds implementation for GET /functions/:id * fix: get function by id or name instead of schema * Update src/lib/PostgresMetaFunctions.ts Co-authored-by: Bobbie Soedirgo <bobbie@soedirgo.dev>
