feat: add ASX corporate actions endpoint

[alexpipipi]

Summary

Adds an SDK wrapper for the ASX Corporate Actions endpoint GET /api/asx-corporate-actions.

Mirrors the paginated-endpoint pattern used for the Sanctions / Credit & Sovereign Risk / Interest Rates endpoints (bare query params, page[offset]/page[limit] pagination, JSON:API { data, meta, links } envelope).

Endpoint

GET /api/asx-corporate-actions — 1 API call per request.

Query params (bare, not filter[...]):

• type — enum: dividends, splits, bonus-issues, rights-issues, buybacks, capital-returns, spp, other
• symbol — ASX ticker with .AU suffix, e.g. PMV.AU
• date_from / date_to — YYYY-MM-DD
• page[offset] (default 0), page[limit] (1-1000, default 100)

Changes

• eodhd/APIs/ASXCorporateActionsAPI.py — new ASXCorporateActionsAPI with get_corporate_actions(); type-enum + pagination-bounds validation, URL-encoded bare params, blank/None params omitted.
• eodhd/APIs/__init__.py — register the new API class.
• eodhd/apiclient.py — APIClient.get_asx_corporate_actions() facade delegating to the API class.
• tests/test_asx_corporate_actions.py — 10 tests (URL/token/fmt, bare-params + no filter[], envelope keys, type lowercasing, hyphenated enum, invalid type, symbol URL-encoding, blank omission, pagination bounds, facade delegation).

Testing

python3 -m pytest tests/ — 80 passed (10 new). Envelope shape and endpoint live-verified.

Usage

from eodhd import APIClient

client = APIClient("YOUR_API_TOKEN")
resp = client.get_asx_corporate_actions(type="dividends", symbol="PMV.AU", page_limit=50)
data = resp["data"]

Bridge AI pre-merge review (Codex GPT-5.4 + Gemini Pro)

No genuine blockers. One flag on uri="" trailing-slash → live-verified HTTP 200 and matches the SDK-wide BaseAPI URL convention. Other notes (date-format validation, Enum class) intentionally left to match the mirrored thin-wrapper template (Sanctions/Credit-Risk from PR #74). pytest: 80 passed.
