The CI workflow already passes --partition-table to espflash save-image (18a0cd5), but the local cargo runner was still using the default partition layout, causing flash failures for the 1.4MB firmware binary. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Context
The firmware binary is ~1.5MB, which exceeds the default ESP32 partition layout (1MB app). The CI workflow already passes --partition-table to espflash save-image (18a0cd5), but the local
cargo runner config was never updated to match. This caused cargo espflash flash to fail with image_too_big on every local flash attempt.
