feat: import exported boards

[mateo-ivc]

Description

Since we have an export feature it would make sense to be able to import those boards again. Therefore, when creating a new board, there is now an option to import a JSON file that reflects a board.

Changelog

Backend

api/router.go

• Added import route

api/boards.go

• Implementation of import board route
• Parses the json string into the components that will be inserted into the database

dto/...

• Added structs to parse the JSON data into usable structs.

database/notes.go

• Added a query to import notes

services/notes.go

• Added import method for notes -> calls importNote in the DB layer.

Frontend

api/boards.ts

• Implementation of importBoard route -> sends json string

Note/NoteAuthorList

• Added authorID of note to be able to create a avatar prop based on the authorID

PassphraseModal

• Popup that asks for a password when importing a previously password-protected board.

constants/name.ts

• Since imported Notes with the same author should have the same avatar and name, i implemented a function that returns a random name with seed

NewBoard

• Added a new button to import a board by drag and drop or by selecting a file.
• Asks for password if board was prior password protected
