Fix misleading weekly reward previews

[XxFran10xX]

The weekly reward tooltip lists every weighted entry, making alternative payouts look cumulative. Summarize amounts by item as a range (for example x2–8 Ignitium), and explicitly label the number of independent random draws and their alternatives.

The planned Act 1 pool fits in three material lines, with per-draw ranges of 20–80 Ignitium, 2–8 raw tin and 2–8 abyssalite fragments. Draw counts follow the multiplier pool whitelist; fixed rewards retain their multiplied amount. Command/bundle outcomes retain their descriptions, and large pools show at most four options plus a remaining count. No reward pools, probabilities or payouts change.

Validation:

• Reviewed the complete diff and passed Java 21 mvn clean verify: 786 tests, no failures or skips.
• Development CI passed at commit 12453c6 (run 36746234251); inspected the timestamped JAR and its embedded version.
• Installed that CI artifact on TFMCDev01 (Paper 1.21.10-130), restarted the empty dev server and verified Activity enabled with its integrations.
• A protocol test client opened the actual GUI and verified the tooltip says One random reward from: and x2–8 Ignitium, with the raw tier lines removed. Existing messages.yml works via packaged defaults.
• Mixed Act 1 ranges, skin pool whitelist, claim prompts, empty/large pools, bundles/commands, and item-based bounds are covered by tests. The Act 1 proposal remains unapplied.

📝 Walkthrough

Walkthrough

Weekly-reward lore now summarizes reward-pool options and shows previews for the next milestone. It uses configured pool eligibility to determine draw counts, limits the displayed options, and provides messages for unavailable previews and undisplayed options.

Changes

Weekly Reward Preview

Layer / File(s)	Summary
Summarize reward options src/main/java/net/tfminecraft/activitytf/gui/RewardPreview.java	RewardPreview.summarize skips entries with nonpositive weight. It groups eligible single-item entries by item path and normalized label, tracks amount bounds, and preserves other display options in insertion order with duplicate labels removed.
Show previews in weekly-reward lore src/main/java/net/tfminecraft/activitytf/gui/ActivityGui.java, src/main/resources/messages.yml, src/test/java/net/tfminecraft/activitytf/gui/ActivityGuiTest.java	ActivityGui passes configured multiplier pools to weeklyRewardLore. The lore uses summarized options and shows up to four displays, with messages for empty previews and undisplayed options. Tests cover quantity ranges, distinct items, reward descriptions, preview limits, and empty pools.

_{A rabbit counts the prizes bright,
And groups the carrots by their size.
Four choices hop into the light,
More wait beyond the preview’s eyes.
The weekly page now tells the tale.}
