fix: correct Somnia's SPOT_PRICES_SUPPORT_INFO slip44 identifier

[maxime-oe]

Somnia (eip155:5031/0x13a7) was registered with the invented slip44:11111 placeholder (slip44:111115031) because no real SLIP-44 registry entry existed at the time. satoshilabs/slips now lists a real entry (5031 = SOMI = Somnia), independently confirmed by the partner. Same pattern as Arc's slip44:5042 entry.

Changelog PR link uses a PR_NUMBER placeholder -- fill in once opened.

Note

Low Risk
Single-chain identifier correction in token price configuration; no auth, persistence, or API contract changes beyond aligning Somnia native price lookups with the canonical asset id.

Overview
Corrects the Somnia (5031 / 0x13a7) entry in SPOT_PRICES_SUPPORT_INFO in codefi-v2.ts: the native asset CAIP reference changes from eip155:5031/slip44:111115031 (temporary 11111<chainId> placeholder) to eip155:5031/slip44:5031, matching the official SLIP-44 registry entry for SOMI.
