Dw add acceptance email

[denniwang]

^ screenshot of what the email looks like.

• created lambda function for sending acceptance letters
• added trigger for sending letters in application service, triggers if application status is changed to accepted
• some formatting

Suggested change

	const site = await this.siteService.getSite(applicationData.siteId);
	const site = await this.siteService.getSite(applicationData.siteId.N);

Don't forget the .N to extract the number!

Im getting this ts error when I add .N,

[denniwang]

I added .N to the userid and siteid from the updateapplication function and that seemed to work because thats the one retrieving from dynamo

Suggested change

	const user = await this.userService.getUser(applicationData.userId);
	const user = await this.userService.getUser(applicationData.userId.N);

Same thing here

[hams7504]

Suggested change

	const siteIds = data['siteIds'].L.map((item) => Number(item.N)) ?? [];
	const siteIds = Array.isArray(data["siteIds"]?.L)
	? data["siteIds"].L.map(item => Number(item.N))
	: [];

You might have to make this change to remove this error: Cannot read properties of undefined (reading 'map')

This PR seems close to being done! Just a couple things left

Also make sure that the userId of the user is given to the user in the acceptance email as they will be using their userId to register/create their account.
