Fix FireRed showmonpic and battle frame types

[Lokesh-shiva]

Summary

• Fix FireRed showmonpic placement so script coordinates match the retail outer-frame origin.
• Generate and use all 10 FireRed user-selected battle Frame Types for the action, move, and message panels.
• Bump the ROM cache format to v339 so per-frame battle panel assets regenerate correctly.

Verification

• Compared showmonpic behavior directly with pokefirered and verified the outer box is 10,3 (10x10 tiles) with the YES/NO box meeting it edge-to-edge without overlap.
• Forced a fresh FireRed v339 import and verified 10 generated frameImages sets.
• Live battle runtime checks passed for Frame Types 1, 2, and 10.
• Independently verified Frame Type 1 vs 10 on both the command menu and move-selection screen.
• Verified legacy-cache fallback with frameImages absent while gen3Frame=10.
• git diff --check passes.

Scope

• Only 4 production files are included in this PR.
• tools/rom_manifest_firered.json is unchanged.
• Screenshots, videos, generated cache data, and scratch validation drivers are not committed.
• The historical player/NPC pixel-line report was not reproducible in the scenes rechecked here and is not claimed as fixed by this PR.

Note: the repository-wide Bash wrapper could not run on this Windows host because WSL has no installed distribution and no standalone Lua/LuaJIT is on PATH; the modified FireRed paths were instead exercised through focused real LOVE runtime/import validation.
