Managing the API endpoints

[yagozk]

While the frontend-backend connection is being established, make necessary changes (add new endpoints, update existing ones etc.) as needed.

• [x] There should be separate "openingTime" and "closingTime" attributes in a business, not a "workingHours" attribute
• [x] Implement "isOpen" as an attribute of a business. This will be calculated for each business as a boolean whenever the endpoint for getting all businesses (/api/buyer/view-businesses) is called.
• [x] Similar to "isOpen", it would be better if we can put a "rating" attribute to a business, which will be computed (when we need to send the data) by the average of all of the reviews of the business. Make sure to handle the case where there are no reviews.
• [x] An offer should have a list of pickup options, e.g. pickUpTimeOptions: ["16.00-17.00", "17.00-18.00"...] (this means that "addOffer" logic also needs to be modified to take pickup options as input from frontend)
• [x] (ege will look into this) Change the "mark offer as sold" logic as we discussed before. (See the top of the google docs for APIs)
• [x] (nevermind, turns out this is fixed) Something wrong with the id field when adding an offer (check the screenshots in the groupchat for this)
• [x] There should be an endpoint for the customer to get their current active reservations.
• [x] In a business, "locationCoordinates" shouldnt't be just a single string, it should be two attributes: latitude and longitude
• [x] In customer, there should be an endpoint for removing a business from your favorites (un-favoriting)
• [x] NullPointer exception in this endpoint [/api/buyer/business/{businessId}/offers] while returning empty offers
• [x] Make the JWT tokens' expiry date a very distant date so they never expire
• [x] Add a logout endpoint
• [x] There should be some endpoints: one GET endpoint for getting all the profile information of a business (name, email, password, phone, opening and closing hours, etc.), and one PUT endpoint for updating these fields
• [x] Add a "logo" field to a business, which will be just a string, like "logo:"string"". Base64 strings will be kept in here, and they will be transformed into pictures in frontend.
• [x] Make sure that "offers" field of a business is returned in the /view-businesses api (it's already returned in the /favorites api)
• [x] Make sure that "open" field of a business is returned in the /favorites api (it's already returned in the /view-businesses api)
• [x] There should be an endpoint for a customer/buyer to cancel a reservation
• [x] Make sure that [/api/buyer/reservations] returns actual information, not IDs. It should return these: id (ID of reservation), seller name, offer name, offer price, timeslot
• [x] Remove isReserved boolean from Offer

• [x] after seller/update updates seller, get seller/{seller} does not work.
• [x] authorization in get seller/{seller}, currently any id passed, returns its userdata
• [x] in seller/{seller}/offers, there is only reservationID returned in reservations field for the offer. reservationTime and customer name should also be included.
• [x] /api/seller/{seller}/history only returns transactionIDs, if exists, comment & rating, customerName, date, offername atc should be returned.

• [x] authorization in get seller/{seller}, currently any id passed, returns its userdata
• This is not a problem, it only gets public seller info for now.
