* [RL] Support chunked part files loading in IPC snapshot strategy
## Motivation
When using IPC snapshot for elastic recovery in RL training, loading a single large pdparams file causes a significant memory spike. This PR refactors `_update_ipc_snapshot` to support loading chunked part files to avoid the memory spike.
## Modifications
Refactored `_update_ipc_snapshot` in `fastdeploy/rl/dynamic_weight_manager.py` with a three-level loading priority:
1. **Chunked part files** (`model_state.tpR{id}.part{N}.pdparams`): Load multiple smaller shards sequentially, freeing memory between each chunk via `gc.collect()` to avoid memory spike.
2. **Single full file** (`model_state.tpR{id}.pdparams`): Legacy single-file loading path (preserved for backward compatibility).
3. **Shared fallback directory** (`/shared_ipc_meta/...`): Oldest legacy fallback path (preserved for backward compatibility).
Also fixed the rank ID in the file name pattern from hardcoded `tp0` to dynamic `paddle.distributed.get_rank()`.
## Checklist
- [ ] Add at least a tag in the PR title.
- [ ] Format your code, run `pre-commit` before commit.
- [ ] Add unit tests. Please write the reason in this PR if no unit tests.
- [ ] Provide accuracy results.
- [ ] If the current PR is submitting to the `release` branch, make sure the PR has been submitted to the `develop` branch, then cherry-pick it to the `release` branch with the `[Cherry-Pick]` PR tag.

* [RL][BugFix] Fix ambiguous model path format and add legacy fallback in IPC snapshot
## Motivation
The previous snapshot file naming `model_state.tp{rank}{id}` concatenated
rank and id without a separator, causing ambiguity (e.g., rank=1, id=234
and rank=12, id=34 both produce `tp1234`). Additionally, after the naming
format is updated, existing checkpoints saved in the old format would fail
to load during elastic recovery, causing unnecessary failures.
## Modifications
- Add dot separator between rank and id in snapshot file name:
`model_state.tp{rank}{id}` → `model_state.tp{rank}.{id}`
- Add Priority 3 legacy fallback to load old-format files
(`model_state.tp0{id}.pdparams`) for backward compatibility during
rolling upgrades
- Update docstring and error message to reflect the new 4-level priority

* [RL][Test] Add unit tests for DynamicWeightManager._update_ipc_snapshot
Cover all 4 loading priority branches (chunked part files, single full
pdparams, legacy format, shared directory fallback) with mock-based
tests to verify correct behavior without filesystem or GPU dependencies.

* [RL] Fix snapshot part index to match filename numbering
Parse part index from filename (e.g. .part0.) instead of using
enumerate index, so that logs and src_type stay consistent with
the actual file naming convention.
