Muhammad Furqan 83540185e1 fix(agent/tools): port AkShare to ToolBase so it works as an Agent tool (#16417 )

### What problem does this PR solve?

Closes #16416.

The **AkShare** agent tool (`agent/tools/akshare.py`) was never ported
to the modern `ToolBase`/`_invoke` interface during the agent module
redesign and was still written against the removed legacy
`_run`/`be_output` API, so it was non-functional:

1. **Adding it to an Agent raised `AttributeError`.** `AkShare` extended
`ComponentBase` (not `ToolBase`) and `AkShareParam` defined no `meta`,
so it had no `get_meta()`. `agent/component/agent_with_tools.py` builds
each tool's function descriptor via `cpn.get_meta()`, so constructing an
Agent that includes the AkShare tool raised `AttributeError: 'AkShare'
object has no attribute 'get_meta'`.
2. **It could never run.** `invoke()` dispatches to `self._invoke`, but
`AkShare` only implemented the legacy `_run`, so `_invoke` fell through
to `ComponentBase._invoke` → `NotImplementedError`. `_run` also called
`be_output(...)`, which no longer exists on the base classes.

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)

### Changes

- Port `AkShareParam` to `ToolParamBase` with a `ToolMeta` (defined
before `super().__init__()`, matching `ArXivParam`/`TavilyExtractParam`)
exposing a required `query` parameter — the stock symbol to look up,
default `{sys.query}`. `query` matches the `{sys.query}` convention
shared by the other tools.
- Rewrite the component with `_invoke`/`set_output("formalized_content",
...)` (errors surfaced via `_ERROR`), keeping `top_n` and importing
`akshare` lazily.
- Add regression tests
(`test/unit_test/agent/component/test_akshare.py`) covering param
construction, validation, and the tool descriptor.

Same class of defect as #16329 (DeepL) and #16414 (Crawler).
Backend-only; no frontend changes.
