Add js-base64 library for Base64 encoding/decoding and enhance password management features. Update axios.js to use Base64 for encoding site key and namespace password. Implement password hint functionality in NamespaceAccess and NamespaceSettingsCard components, including dialogs for setting and verifying password hints. Refactor kvServerProvider to support password hint updates during password management operations.
