Add Clock widget

# What
- Add Clock widget type.

# Why
- Add Clock widget to show clock in the current area so the user get a solid data.

## Weather widget
- We want to show the local time or in a specific area the user picks.

# Definition of done

### Client
- Add new clock widget
- Select from different types of clocks, digital and analog
- Data will be collected after save

### Backend
- Backend needs to call an api if the card has no time data
- Backend needs to collect data from the database if the card has time data
- Ratelimiter is needed in order to not collect data from our weather API all the time
- Time data should be stored in a seperate table
- Time data Is stored by location
- If Time data already excites by location, we dont need to collect it again, just link it to the card
- Add new endpoint for widget
- Add new repository for widget

No files, tests, or entry points are named. Start by mapping the existing weather widget's client, backend endpoint, repository, database, and rate-limiting flow. Done means supporting local or selected-area time, digital and analog clock choices, stored location data, reuse of existing data, and the requested new widget endpoint.
