build(deps): bump milvus-proto to ae7fea6a

[MrPresent-Han]

issue: #3790
related pr: #3791

Scope

Upgrade PyMilvus's complete protocol baseline separately from the SDK API implementation in #3791.

• Advance the proto submodule from 0fb0d5bcf2e2ff4dff30683e5aa0f8991a20d011 directly to ae7fea6ab2f4e958f2feef0f0edb9a0d23fa7e0c.
• Include the merged compaction protocol changes from feat: expose compaction lifecycle observability metadata milvus-proto#668: public task-state/type enums, retained segment lifecycle filtering and lineage, collection task selectors, failure reasons, and complete task targets.
• Include the other upstream protocol updates between these commits for UUID/nested arrays, RLS, snapshot export, import metadata, and shard routing.
• Regenerate the Python messages, typing stubs, and service bindings with the repository generator and pinned grpcio-tools==1.66.2.
• Change only the proto submodule and its nine generated files; no handwritten SDK logic, tests, generators, or dependency constraints are changed.

Relationship to #3791

This PR now contains the full protocol bump, including compaction metadata; it no longer stops at the pre-compaction revision.

Merge this PR first, then rebase #3791 onto master so that #3791 contains only six SDK implementation files and five unit-test files.

The entire pymilvus/grpc_gen tree, including the proto submodule pointer, matches #3791 exactly, so all ten protocol-related entries disappear from that PR's diff after the rebase, reducing 21 changed files to 11 without changing SDK behavior.

Validation

• The complete protocol tree matches enhance: add compaction lifecycle observability APIs #3791 byte-for-byte.
• No handwritten code or tests differ from master in this PR.
• Repeating generation produces no diff, and git diff --check passes.
• Complete tests/unit run on the full ae7fea6a baseline: 4,718 passed, 3 skipped, 1 failed in 54.42 seconds.
• The only failure is tests/unit/orm/test_types.py::TestInferDtypeBydata::test_numpy_like_with_dtype_returns_float_vector (FLOAT inferred versus expected FLOAT_VECTOR), which was independently reproduced on unchanged trunk/master at a4b3b38bbd8baa4c1047dccb7647a3bc47defcdb in the same environment during the baseline preparation; no unrelated SDK or test fix is included.
• This is protocol-generation and unit-test verification, not Milvus server E2E verification.
