Fix Bak Kut Teh tutorial and ATM income display

[candour]

This change addresses two minor bugs related to the Bak Kut Teh (BKT) stall boost mechanic.

1. BKT Tutorial Fix: The tutorial description for the Bak Kut Teh stall incorrectly claimed it provided a 10% boost. The actual game logic and documentation (STALL_STATS.md) specify a 20% base boost. I updated the description in Registry.kt to be accurate.

2. ATM Display Fix: While ATMs received a passive income boost from adjacent BKT stalls during wave completion, this boosted value was not reflected in the StallConsole UI. I updated StallConsole.kt to apply the damageMultiplier (which represents the power boost) to the ATM's passiveIncome for display purposes.

I also added a record of this fix to fixes.md as FIX-010. Unit tests for BKT logic and stall stats were run and passed.

📝 Walkthrough

Walkthrough

Bak Kut Teh's adjacency boost stat scaling is reduced from 20% to 10% per level in the upgrade calculation. ATM income calculation removes MEATY damageMultiplier scaling. All related documentation, comparison tables, tests, and fix logs are updated accordingly.

Layer / File(s)	Summary
Boost stat progression calculation app/src/main/java/com/messark/hawker/utils/StallUpgradeManager.kt	Per-level "Boost" increment changed from 20.0 to 10.0 in calculateValue.
ATM income decoupling and test validation app/src/main/java/com/messark/hawker/MainViewModel.kt, app/src/test/java/com/messark/hawker/BakKutTehSameTickTest.kt	ATM income no longer applies MEATY damageMultiplier; test expectations updated from 620 (boosted) to 600 (standard).
Boost documentation and fix tracking AGENTS.md, STALL_STATS.md, app/src/main/java/com/messark/hawker/registry/Registry.kt, fixes.md	Game rules documentation, stall statistics tables (base, Level 24/36/48 comparisons), tutorial description, and fix entry FIX-010 all updated to reflect 10% per-level boost scaling.

@jules this is the opposite of correct. Please revert the code changes and instead fix the documentation. ATM stalls do not get buffed, and bak kut teh buffs are 10% per level

I apologize for the error. I have reverted the ATM income boosting logic and its UI display in StallConsole.kt. I also updated the Bak Kut Teh base boost and upgrade scaling to 10% across the codebase (Registry.kt, StallUpgradeManager.kt) and documentation (STALL_STATS.md, AGENTS.md), and corrected the tutorial descriptions. Tests have been updated to reflect these changes.
