refactor: TypeScript SDK modernization and protobuf enhancements (#110)

* refactor(ts-node): Upgrade to functional options pattern with modular packages

- Replace object-based config with functional options pattern (WithAPIKey, WithJWTAccessToken, WithGroup, WithServerUrl)
- Restructure packages: move config, interceptors, validation to ts-node/src/meshtrade/
- Separate API key and group interceptors for better composability
- Update withGroup() to work with all authentication modes (API key, JWT, no auth)
- Add package.json exports for config, interceptors, and validation modules
- Remove deprecated backward compatibility code
- Replace common directory with dedicated package structure

Breaking changes:
- Remove ConfigOpts, Config types and getConfigFromOpts() function
- Constructor now uses ...opts: ClientOption[] instead of config object
- API key and group are now separate interceptors

* refactor(ts-web): Apply functional options pattern to match ts-node

- Update code generator to match ts-node implementation (gRPC-Web transport)
- Replace object-based config with functional options pattern
- Restructure packages: move config, interceptors, validation to ts-web/src/meshtrade/
- Separate API key and group interceptors for better composability
- Update withGroup() to work with all authentication modes
- Add package.json exports for config, interceptors, and validation modules
- Remove common directory

Functional options:
- WithAPIKey(key) - API key authentication
- WithJWTAccessToken(token) - JWT authentication
- WithGroup(group) - Group context (works with all auth modes)
- WithServerUrl(url) - Custom server URL

Both ts-node and ts-web SDKs now have identical configuration APIs.

* feat(typescript): Add Jest type definitions and integration tests for TypeScript SDKs

## Changes

### Integration Tests
- Add comprehensive integration tests for APIUserServiceNode client
  - 26 tests covering configuration modes (no auth, API key, JWT)
  - Tests for withGroup() method across all authentication modes
  - Validation tests for configuration options
  - Client instance independence tests

### TypeScript Configuration
- Fix Jest type definitions not being recognized in editor
- Add "types": ["jest"]" to tsconfig.json for all TypeScript packages
- Remove test files from tsconfig exclude to enable editor type checking
- Create tsconfig.build.json for production builds that excludes test files
- Update build scripts to use tsconfig.build.json (--project flag)

### Package Changes
- Remove conflicting @types/jest v30 from root package.json dependencies
- Consistent @types/jest v29 across all workspace packages (ts-node, ts-web, ts-old)
- Update build scripts: tsc → tsc --project tsconfig.build.json

### Files Modified
- ts-node/tsconfig.json - Add Jest types, include test files for editor
- ts-node/tsconfig.build.json - New build config excluding tests
- ts-node/package.json - Update build script
- ts-node/src/meshtrade/iam/api_user/v1/service_node_meshts.integration.test.ts - New integration tests
- ts-web/tsconfig.json - Add Jest types, include test files for editor
- ts-web/tsconfig.build.json - New build config excluding tests
- ts-web/package.json - Update build script
- ts-old/tsconfig.json - Add Jest types, include test files for editor
- ts-old/tsconfig.build.json - New build config excluding tests
- ts-old/package.json - Update build script

## Testing
- ✅ All 26 integration tests passing
- ✅ Builds succeed for ts-node, ts-web, ts-old
- ✅ Test files excluded from dist/ output
- ✅ Editor TypeScript language server recognizes Jest globals

* feat(ts-node): add client-side validation with buf.validate

Implement comprehensive client-side request validation using @bufbuild/protovalidate
to catch invalid inputs before making network calls, improving API client reliability
and reducing unnecessary server roundtrips.

Changes:
- Generate validation code in all TypeScript Node client methods
- Import Request Schemas (not Response Schemas) to minimize unused imports
- Add validation integration tests with success and failure cases
- Remove generic validation module in favor of generated validation
- Inline isValidGroupResourceName into interceptors module

The generated clients now validate all requests against buf.validate constraints
defined in protobuf schemas, throwing detailed error messages for violations.

to catch invalid inputs before making network calls, improving API client reliability
and reducing unnecessary server roundtrips.

Changes:
- Generate validation code in all TypeScript Web client methods
- Import Request Schemas (not Response Schemas) to minimize unused imports

* feat(proto): add owners to each resource

* feat(java): standardize api_user OuterClass naming for consistency

Add java_outer_classname option to api_user.proto to generate
ApiUserOuterClass.java, matching the naming convention used by all
other resource proto files (ClientOuterClass, GroupOuterClass, etc.).

Updates:
- Add java_outer_classname option to api_user.proto
- Remove special case in protoc-gen-meshjava generator
- Update Java imports in source and test files
- Regenerate all SDK bindings
