feat(statics): expose bech32 HRP via AccountNetwork.addressPrefix

Add optional `addressPrefix?: string` to `AccountNetwork` interface so
downstream consumers (e.g. the BFF address-poisoning detector, WCN-607)
can strip well-known bech32 HRPs before Levenshtein comparison.

`CosmosNetwork` already requires `addressPrefix: string`; adding the
optional field to its parent `AccountNetwork` is purely additive.
Populate the new field for all Cosmos-family AccountNetwork classes
that previously hid their HRP in per-coin constants.ts files. All
values verified against github.com/cosmos/chain-registry.

Mainnet+testnet (same HRP):
- atom -> cosmos
- osmo -> osmo
- sei -> sei
- tia -> celestia
- baby -> bbn
- bld -> agoric
- initia -> init
- zeta -> zeta
- asi -> fetch
- islm -> haqq
- injective -> inj

Mainnet/testnet (asymmetric):
- hash -> pb / tp
- coreum -> core / testcore
- cronos -> cro / tcro
- rune -> thor / sthor

kava/dydx/mantra already have addressPrefix via CosmosNetwork;
tests added for completeness. fetchai is deprecated -- skipped.

Ticket: WCN-606
