[BOT ISSUE] Mistral: add missing Ministral 3 family models (ministral-14b, ministral-3b)

[github-actions]

Gap

Two new Ministral 3 family models are completely missing from packages/proxy/schema/model_list.json: ministral-14b-latest / ministral-14b-2512 and ministral-3b-latest / ministral-3b-2512. Additionally, the dated snapshot ministral-8b-2512 is missing (though ministral-8b-latest exists with stale pricing).

The catalog has the old Ministral generation (ministral-8b-latest at $0.10/$0.10 and ministral-8b-2410), but the new Ministral 3 family introduced in December 2025 added 14B and 3B models that are not represented.

• ministral-8b-2512 — new dated snapshot of Ministral 3 8B ($0.15/$0.15, parent: ministral-8b-latest); the existing ministral-8b-latest entry has stale pricing ($0.10/$0.10 → should be $0.15/$0.15)

Verification notes

• Cross-source: Each model ID confirmed on (1) Mistral models overview page and (2) dedicated model card detail page with pricing — two independent official signals.
• Recent commits: No ministral-14b or ministral-3b entries exist in model_list.json. Existing Ministral entries are ministral-8b-latest (line 5016) and ministral-8b-2410 (line 5023).
• ID format: ministral-{size}-latest / ministral-{size}-2512 matches existing Mistral convention (e.g., ministral-8b-latest, ministral-8b-2410).
• No duplicate issue: No existing [BOT ISSUE] references ministral-14b or ministral-3b.
