fix: update imports for major dependency upgrades (bech32 v2, @noble/hashes v2, bs58 v6, @noble/curves v2, chain-registry v2)

[pyramation]

Summary

Fixes type and import errors caused by major dependency version bumps on the feat/upgrades branch. No logic changes — only import paths, export styles, and property name casing were updated to match new library APIs.

Dependency	Breaking Change	Files Affected
bech32 v2	namespace → named export	packages/encoding/src/bech32.ts
@noble/hashes v2	sha256/sha512 moved to sha2; ripemd160 moved to legacy	packages/crypto/src/sha.ts, pbkdf2.ts, ripemd.ts, packages/auth/src/utils.ts, built-in.ts
bs58 v6	namespace → default export	4 files in networks/solana/
@noble/curves v2	Signature.fromCompact() → fromBytes(_, 'compact'); toRawBytes() → toBytes()	networks/ethereum/src/signers/base-signer.ts
@chain-registry v2	snake_case → camelCase (bech32_prefix, chain_name, chain_1/chain_2, port_id, channel_id)	4 starship test files

Review & Testing Checklist for Human

• Verify @noble/curves v2 API: The secp256k1.Signature.fromBytes(bytes, 'compact') and point.toBytes(false) calls in networks/ethereum/src/signers/base-signer.ts are the highest-risk change — confirm these match the actual v2 type signatures (runtime failure in ETH signing if wrong)
• Indentation drift: The diff shows some lines in base-signer.ts (lines 212-213, 268-269) and the IBC test blocks in token.test.ts picked up extra indentation during editing — verify these don't cause linting issues or are acceptable
• Chain-registry camelCase in test files: The starship test changes (bech32Prefix, chainName, chain1/chain2, portId, channelId) can't be validated without a starship environment — spot-check against @chain-registry/types@2 type definitions
• Run pnpm build to confirm all packages compile (injective has a pre-existing unrelated error)

Notes

• Lint is broken repo-wide due to an ESLint / @typescript-eslint version incompatibility — pre-existing, not introduced here
• The networks/injective build error (src/signers/config.ts type mismatch) also pre-exists on main
