Add PostsMixin with 15 methods:
- create_post, get_post, update_post, delete_post
- send_ephemeral_post, update_ephemeral_post, delete_ephemeral_post
- get_post_thread, get_posts_since, get_posts_after, get_posts_before
- add_reaction, remove_reaction, get_reactions
All methods follow the established mixin pattern with proper error
handling and type annotations.

- Reaction: User emoji reaction to a post
- PostList: Ordered list of posts with pagination

This was missing from the previous mixin implementation commit.

Generate Python code from server/public/pluginapi/grpc/proto:
- Protocol buffer message definitions (*_pb2.py)
- gRPC service stubs (*_pb2_grpc.py)
- Type stubs for IDE completion (*_pb2.pyi, *_pb2_grpc.pyi)
- Imports fixed to use package-relative imports
Generated from 18 .proto files using grpcio-tools and mypy-protobuf.

Add client classes for Mattermost Plugin API:
- PluginAPIClient: sync client with context manager support
- AsyncPluginAPIClient: async client with grpc.aio support
- Both implement get_server_version() as smoke test RPC
- Proper error handling converts gRPC errors to SDK exceptions
