chore: increase price weight in routing score

[steebchen]

Summary

• Bumps PRICE_WEIGHT from 0.3 → 0.6 and IMAGE_PRICE_WEIGHT from 0.5 → 1.0 in packages/actions/src/get-cheapest-from-available-providers.ts.
• Makes price the single largest weighted-score factor (0.6 vs uptime 0.5, cache 0.2, throughput 0.05, latency 0.025).
• Note: total non-price weights still sum to 0.775, so other signals retain meaningful influence — this is an intentional, conservative bump rather than fully price-dominant routing.

Test plan

• pnpm format
• pnpm build
• Spot-check provider selection in staging for representative models

Walkthrough

This PR modifies the provider selection routing logic by increasing price weighting in the scoring algorithm. The PRICE_WEIGHT constant rises from 0.3 to 0.6, and IMAGE_PRICE_WEIGHT increases from 0.5 to 1.0, making cost a more significant factor when comparing available providers.

• theopenco/llmgateway#2095: Both PRs modify the provider-selection weighted-scoring logic in packages/actions/src/get-cheapest-from-available-providers.ts—one changes the price-related weight constants, and the other adds a prompt-caching term/weight gated by promptTokens, so they directly overlap in the same scoring pathway.
