Refactor context passing: pipeline now accepts dict directly

Eliminate the NamedTemporaryFile workaround in server.py by adding a
`context` dict parameter to run_freshrss_pipeline. The pipeline resolves
filter context from the dict first, falling back to context_path, then
defaulting to an empty FilterContext. Remove unused json/tempfile imports.

-- [ ] `server.py` context 通过临时文件传递绕路 — `run_freshrss_pipeline` 改为同时接受 `dict | Path` 类型的 context，消除 `NamedTemporaryFile` 绕路
+- [x] `server.py` context 通过临时文件传递绕路 — `run_freshrss_pipeline` 改为同时接受 `dict | Path` 类型的 context，消除 `NamedTemporaryFile` 绕路（已修复）
 - [ ] `_load_required_env` 报错信息不区分"未传参数"还是"环境变量未设"，改善调试体验
 - [ ] `evaluate_filter_rules` 决策逻辑歧义 — `stop_on_match=True` 命中后应直接以该规则 decision 为最终结果，而非继续聚合所有 matched
