Survival mode UX fixes

[tejush1998]

closes #188

Summary

Change 1 : Inspect the board on game over + minimizable failure card

• Basically when i fail a survival game at high RPS, it happens so quickly , i am not able to figure out what caused the failure in the first place. Need a way to see the snapshot of the failure-moment state which i can hover over to see the load on various resources
• Removed the opaque dark/blur overlay on the game-over #modal so the frozen board stays visible. The modal is now pass-through (pointer-events-none) with only the result card interactive (pointer-events-auto), letting you hover services to read their load/queue/health at the moment of failure.
• Added a minimize button (─) to the failure card and a floating "⚠ Show Results" restore pill, via new window.toggleFailureModal(). Collapsing the card fully clears the board for inspection; the card always reopens expanded on a fresh failure.

Change 2: Failures list "Clear" updates immediately

• So whenever i pressed the clear button for failures. It wasnt instant. Only when a new failure occurred, it started from 0. Otherwise the clear button looked like it was broken.
• Clicking Clear previously only zeroed STATE.failures; the panel didn't refresh until the next failure (the render block is gated on totalFailures > 0). It now hides the panel and resets the total to 0 right away.

Change 3: Restore auto-repair state on Continue (load saved game)

• Tried several times continuing saved game to reach higher RPS. But each time I had to enable auto repair. Which doesnt make sense. Its better to load it from previous state.
• loadGameState hardcoded STATE.autoRepairEnabled = false, discarding the saved value. It now restores the flag from the save and syncs the Auto-Repair toggle button (ON/OFF text + color).

i18n

• Added minimize and show_results keys across all 9 locales (en, de, fr, it, ko, nep, pt-BR, ru, zh).
