Save Project to local database

[thehabes]

Projects will be saved into the local mongo database Projects collection (identified in .env file). A minimal project will look something like this:

 {
    "_id": {
        "$oid": "65f48b254da4e4b8c656d0d1"
    },
    "slug": "exampleProject",
    "creator": "https://store.rerum.io/v1/id/exampleAgent",
    "created": 1,
    "group": {
        "$oid": "65f48c9a4da4e4b8c656d0d2"
    },
    "layers": [ "https://store.rerum.io/v1/id/exampleAnnotationCollection" ],
    "lastModified": "exampleAnnotationPageId",
    "viewer": "https://static.t-pen.org/#65f48b254da4e4b8c656d0d1",
    "license": "CC-BY",
    "manifest": "https://external.example.com/manifest.json",
    "tools": [],
    "options": {},
    "tags": ["gog"],
    "title": "First Project"
}

undefined values do not need to be set and should not be assumed to be present on any Project. This chart explains the expected values and how they are used:

key	type	description	required	notes
_id	ObjectID(hex)	MongoDB generated complex key	✔	This will be generated if not provided, but should be assigned before saving so the Interface can be notified of the location before it clears the queue in the DB driver.
slug	String	slugified from user input as alternate lookup value		This must be unique, but is not required.
creator	URI	Rerum Agent Id of Project owner/creator	✔	Based on auth'ed User, does not change after creation
created	Date Literal	timestamp of the time this Project was created	✔	for sorting and filtering
group	ObjectID(hex)	MongoDB generated complex key	✔	If provided (maybe as a hexstring), can point to an existing Group but must be generated and saved into Groups collection if not
layers	Array of URI	Annotation Collection(s) in RERUM	🥝	Interfaces won't really work without it, but it doesn't need to be added until the first Annotations are added
lastModified	RERUM URI	The most recent Annotation or Canvas manipulated		Not defined on creation
viewer	URL	Interface location for readonly HTML		Static page location once Project is publicly visible
license	String	statement of license	✔	If not defined, default to "CC-BY" which might be added to a config
manifest	URI	IIIF Manifest of source	✔	must preexist or be embedded in the body of a post and created in RERUM
tools	Array	project tools		no default, no rules set for inclusion yet, just Interfaces aid
options	Object	config object for overriding Interfaces defaults
tags	Array of String	open tags		defined by Users or by Interfaces
title	String	unicode title of Project	✔	generate if not provided

Tests should confirm validation checks for new Projects, mock the driver actions, and respond correctly to expected errors or invalid inputs.
