feat: add new endpoints for api

[fabio-nettis]

Description

Exciting changes await! We added some very important new endpoints in this PR that still were missing. Here is what is now available:

Statistics

Statistics for the entire galaxy or a specific planet, this includes number of kills, friendly fire kills etc. Please Note that not every planet has statistics, this is because there may not have been fought a battle on it yet.

• /api/statistics: List all available statistics.
• /api/statistics/:id: Get a specific statistic by id.
• /api/statistics/galaxy: Get the galaxy wide statistics.
• /api/planets/:id/statistics: Get statistics for a planet.

Reports

You can find reports by pressing R2 or the PC equivalent while in your ship. Contain bits of story and lore based on the players actions and performance in the war.

• /api/reports: List all available reports.
• /api/reports/:id: Get a specific report by id.

Assignments

Assignments are Major Orders that are very important to the war progress. It is possible that a given time there is no Major Order and the endpoint will return an empty array.

• /api/assignments: List all available assignments.
• /api/assignments/:id: Get a specific assignment by id.
• /api/assignments/:id/rewards: Get the rewards for a specific assignment.
