fix: price Forma native TIA via zero-address native asset

[jeremytsng]

Explanation

Forma (eip155:984122) is an EVM rollup whose native gas token is TIA (Celestia). assets-controllers currently requests Forma's native spot price as eip155:984122/slip44:984122, a chain-ID-derived SLIP-44 reference.

We should not invent non-canonical SLIP-44 references. SLIP-44 coin types are a registry of real, assigned coin types and are not equivalent to chain IDs (they are not 1:1 — e.g. slip44:56 is EDRCoin, while Binance Smart Chain's native is slip44:714). TIA/Celestia has no registered SLIP-44 coin type, so slip44:984122 is a made-up value, and 984122 could be assigned to another network in the future.

This change switches Forma's native token to the zero-address native convention — eip155:984122/erc20:0x0000000000000000000000000000000000000000 — the same representation already used for other non-ETH natives in SPOT_PRICES_SUPPORT_INFO (e.g. Hemi, BOB, Berachain). The Price API resolves this to the CoinGecko celestia coin via a platform mapping. No SLIP-44 reference is invented, and no chainIdToNativeTokenAddress entry is needed (zero address is the default).

Note

Low Risk
Low risk: a single CAIP-19 mapping change for Forma’s native asset that only affects spot price resolution for chain 984122. Potential impact is limited to Forma native pricing if downstream APIs interpret the zero-address differently.

Overview
Fixes Forma (chain 984122) native token (TIA) spot price resolution by changing its SPOT_PRICES_SUPPORT_INFO entry from slip44:984122 to the zero-address native asset (erc20:0x0000000000000000000000000000000000000000).

Adds a CHANGELOG.md Fixed entry documenting the correction.

This returns nothing in price-api (so does the slip44).

This chain is not supported by price-api. I'm unsure as to why it was added here in the first place, but should be removed.
