Add edge case test for stat wipe in progression calculations

[Copilot]

Adds test coverage for progression calculations when stats decrease from high values to zero/low values, simulating a stat reset/wipe scenario.

Changes

• New test case: edge case: stat wipe covering 65 test combinations (11 gamemode stats × 5 gamemodes + 2 overall stats × 5 gamemodes)
• Test setup:
  • Start player with 100,000 for all gamemode stats and 4,870,000 exp (1000 stars)
  • End player with 0 for all gamemode stats and 500 exp (1 star)
  • Shared builders and history created once at function root for efficiency
• Test coverage:
  • Gamemode-specific stats: gamesPlayed, wins, losses, bedsBroken, bedsLost, finalKills, finalDeaths, kills, deaths, fkdr, kdr
  • Overall stats: experience, stars
• Assertions: Verifies no errors thrown, no error object returned, and endValue matches expected values (0 for gamemode stats, 500 for experience, 1 for stars)
• Excluded stats: winstreak (not implemented), index (not yet supported - noted in code)

The progression calculation handles this edge case gracefully, returning negative progressPerDay for gamemode stats and appropriate values for experience/stars without crashing.

Original prompt

Add a new top level test case in the progression test named "edge case: stat wipe" create a start player with very high stats and an end player with 0 stats. Then loop over all stat keys and all gamemodes and assert that the progression calculation does not throw an error and does not return an error. Also assert that the returned value is 0. Note that since this is an edge case we don't care about the specific behavior, just that it doesn't crash.
Skip "index" as we don't support progression for that yet, but make a note about it

@copilot move the stats and player builders to the root of the function since these are shared and will not be mutated. Also move the history there. Then make an additional loop over exp, stars, and move the todo about index to there. Set the exp on the before player to 1000 stars. And 500 exp on the after player.

Done in 581e5e6. Moved builders and history to function root, added separate loop for experience/stars with 1000 stars (4,870,000 exp) on start player and 500 exp on end player. TODO about index moved to the experience/stars section.
