Switch to secure Base58 library

[r-near]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• Commit messages follow the conventional commits spec
• If this is a code change: I have written unit tests.
• If this changes code in a published package: I have run pnpm changeset to create a changeset JSON document appropriate for this change.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

This PR switches the Base58 implementation to a secure, audited & 0-deps implementation. The existing bs58 library is old, poorly maintained, and incompatible with Vite due to its use of Node.js primitives (Buffer).

This PR should resolve the following:

• Vite: Cannot read properties of undefined (reading 'from') #1420
• npm warn deprecated base-x@2.0.6 #1408
• Use Own Base58 #1391
• Alternate bs58 Upgrade #1392

This project still indirectly relies on bs58 through near-workspaces:

near-workspaces 3.5.0
├─┬ borsh 0.5.0
│ └── bs58 4.0.0
├── bs58 4.0.1

We'll need to do this in parts:

1. First, we need to release new packages for these libraries
2. Then, we need to update near-workspace to use the new libraries that don't depend on bs58, along with stripping the existing bs58 dependency
3. Release a new version of near-workspace with 0 dependency on bs58
4. Bump near-workspace version in near-api-js and make a new release
