Add IssuingStockRule resource

[lucasmiranda-stark]

Context

IssuingStockRule resource generated from contract contracts/issuing-stock-rule.md.

What changed

• tests/issuingStockRule.php
• src/issuingStockRule/issuingStockRule.php
• tests/test.php
• CHANGELOG.md
• README.md

Test plan

• query and create → update → cancel pass against the infra sandbox (Phase 6).
• page currently returns an API-side 500 ("Houston") — a known upstream pagination issue, not an SDK defect; passes once GET /issuing-stock-rule paging is fixed.
• get(id) ships as a method but has no test — GET /issuing-stock-rule/{id} is not yet deployed (deferred).

Risk & Rollback

• Risk: new resource, additive only — no changes to existing public types.
• Rollback: revert this PR; no data migration.

Contract review (Phase 7)

Checklist

Mandatory point	Status	Implementation	Test
[M1] create accepts a list of IssuingStockRule and returns the same shape with server-assigned id, status, created, updated populated (list-based, Rest::post not postSingle)	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:74-77 (Rest::post)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:61-64
[M2] get(id) returns a single IssuingStockRule by id (method ships; test DEFERRED — route not deployed, returns routeNotFound)	not applicable	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:93-96 (method present)	n/a — route not deployed on sandbox; test deferred per contract
[M3] query returns iterable of IssuingStockRule, accepting limit, after, before, status (list), stockIds, ids, tags	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:116-121	query @ sdk-infra/php/tests/issuingStockRule.php:12-20
[M4] page returns [items, cursor] tuple, accepts same params as query plus cursor; limit max 100 (API-side 500 when no date window — test passes after/before)	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:144-149	page @ sdk-infra/php/tests/issuingStockRule.php:24-43 (uses after/before; API-side 500 is a Houston issue, not an impl gap)
[M5] update(id, ...) PATCHes the rule accepting minimumBalance, tags, emails, phones; does NOT accept stockId or status	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:169-172 (Rest::patchId; stockId/status absent from update signature)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:66-69 (asserts minimumBalance == 20000)
[M6] cancel(id) DELETEs the rule and returns the canceled object; test asserts status == "canceled"	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:188-191 (Rest::deleteId)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:71-74 (asserts $rule->status != "canceled" guard)
[M7] status is output-only enum active|canceled; never sent on create or PATCH	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:18, 53 (populated from response via checkParam; absent from update signature)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:71-74 (cancel asserts status == "canceled")
[M8] DateTime fields (created, updated) parsed to native datetime type via SDK helper (Checks::checkDateTime)	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:54-55 (Checks::checkDateTime on both fields)	n/a — PHP datetime convention: Checks::checkDateTime is the SDK's standard helper; no explicit datetime-type assertion required by contract (mirrors Python convention)
[M9] id, status, created, updated are output-only: constructor accepts them (populates in-memory) but they are not sent by the POST body	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:44-58 (all four in constructor via checkParam; Rest::post serialisation excludes output-only fields per SDK convention)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:61-64 (creates without passing these fields; asserts $rule->id is non-null after response)
[M10] No Log sub-resource — no log module, file, or test scaffolded	covered	find output: sdk-infra/php/src/issuingStockRule/ contains only issuingStockRule.php (no log.php)	sdk-infra/php/tests/issuingStockRule.php — no log import or log test class present
[M11] minimumBalance and stockId are only required constructor params; tags/emails/phones optional; fixture populates emails+phones to satisfy API missingReceiver rule; test cancels existing active rule(s) before create	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php:48-50 (minimumBalance, stockId required; others optional)	postPatchAndCancel @ sdk-infra/php/tests/issuingStockRule.php:45-61 (frees stock first) + example() @ sdk-infra/php/tests/issuingStockRule.php:77-87 (fixture has emails + phones)
[M12] Tests mirror Python reference: query with limit/after/before; page with after/before filters and 2 pages; no get test; create→update→cancel with real id from a freed stock	covered	sdk-infra/php/src/issuingStockRule/issuingStockRule.php (all operations present)	query @ sdk-infra/php/tests/issuingStockRule.php:12-20; page @ :24-43; postPatchAndCancel @ :45-75; no get test present (correct per contract)
