add logger

[diegoalzate]

overview

adds a pino logger, this is a very lightweight one.

there are levels of logs shown in the comment, by default it is put to info which means it includes that and everything before that level.

for example to see less you can run:

LOG_LEVEL=fatal pn dev

for tests to see logs you can run

LOG_LEVEL=debug pn dev

• there are still two instances of console.log in /handlers/options.ts
• the tests pass but somehow errors related to the harts ratio are returned:

benedikt@LAPTOP-51EETM3E:~/forum-backend$ pnpm test src/services/questions.spec.ts

[email protected] test /home/benedikt/forum-backend
jest --runInBand "src/services/questions.spec.ts"

 PASS  src/services/questions.spec.ts
  service: forumQuestions
    ✓ calculates available hearts correctly (2 ms)
    ✓ error if max ratio was not calculated correctly
    ✓ returns custom hearts if customHearts is set
    ✓ executes the function if customHearts is not set
    ✓ executes the function if customHearts is set to less than 2
    ✓ that function returns 0 in case the number of proposals are less than 2

• in services/question.ts question_options should be changed to options in the raw sql query.

remove unused dependency: import { logger } from '../utils/logger'; from services/votes
