As part of preparation for ESM and node/TSC updates, this PR will make
Unleash build with strictNullChecks set to true, since that's what's in
our tsconfig file. Hence, this PR also removes the `--strictNullChecks
false` flag in our compile tasks in package.json.
TL;DR - Clean up your code rather than turning off compiler security
features :)
Add new methods to the store behind data usage metrics that accept date
ranges instead of a single month. The old data collection methods
re-route to the new ones instead, so the new methods are tested
implicitly.
Also deprecates the new endpoint that's not in use anywhere except in an
unused service method in Enterprise yet.
## Discussion point:
Accepts from and to params as dates for type safety. You can send unparseable strings, but if you send a date object, you know it'll work.
Leaves the use of the old method in `src/lib/features/instance-stats/instance-stats-service.ts` to keep changes small.
Add support for querying the traffic data usage store for the aggregated data for an arbitrary number of months back.
Adds a new `getTrafficDataForMonthRange(monthsBack: number)` method to the store that aggregates data on a monthly basis by status code and traffic group. Returns a new type with month data instead of day data.
Provides store method for retrieving traffic usage data based on
period parameter, and UI + ui hook with the new chart for displaying
traffic usage data spread out over selectable month.
In this PR we copied and adapted a plugin written by DX for highlighting
a column in the chart:
There are some minor improvements planned which will come in a separate
PR, reversing the order in legend and tooltip so the colors go from
light to dark, and adding a month -sum below the legend
## Discussion points
- Should any of this be extracted as a separate reusable component?

## About the changes
Implements a new store for collected traffic data usage that connects to
the new table `stat_traffic_data` primary key'd on [day, trafficGroup,
status_code_series].
Day being a date
Traffic group being which endpoint is being counted for, ie /api/admin,
/api/frontend etc
Status code series grouping 2xx status responses and 304 into their
respective 200 / 300 series.
No service here, this is for pro/enterprise
