feat: Add Jira Service Management Connector via inheritance (Fixes #2281)

/claim #2281

Description

This PR implements a Jira Service Management (JSM) connector that indexes tickets, requests, and comments from JSM projects, with full EE permission sync support.

Architectural approach: Inheritance over duplication

Rather than copying the 1,066-line Jira connector (as attempted in prior PRs), this implementation inherits from JiraConnector and overrides a single method — _load_from_checkpoint — to re-tag yielded Document objects with DocumentSource.JIRA_SERVICE_MANAGEMENT.

The result is a 45-line connector with zero duplicated logic. All JQL search, ADF parsing, checkpoint pagination, hierarchy node generation, permission sync, and validation are inherited from the battle-tested Jira connector.

Why this works:

process_jira_issue() is the only place that sets source=DocumentSource.JIRA — our override intercepts and re-tags it.
Both load_from_checkpoint() and load_from_checkpoint_with_perm_sync() delegate to _load_from_checkpoint, so a single override covers both paths.
SlimDocument has no source field, so retrieve_all_slim_docs_perm_sync requires no override.
Document is a mutable Pydantic model (not frozen), so item.source = ... is safe.

This follows the codebase’s own best practices: “No duplicate logic: Don’t copy/paste into branches when shared logic can live above the conditional.”

EE Permission Sync Design

A dedicated jira_service_management_doc_sync function was required because jira_doc_sync hardcodes DocumentSource.JIRA and JiraConnector. Without a separate function, the DB lookup during permission sync would search for documents with source JIRA instead of JIRA_SERVICE_MANAGEMENT, resulting in zero matches.

jira_group_sync is safely reused for JSM because it only enumerates Jira groups and does not reference a specific DocumentSource. Both JSM and Jira share the same Atlassian group model.

Issues addressed from automated reviews

Resolved (confirmed by Greptile 4/5 + Cubic):

✅ access.py dead code — Removed entirely; permissions inherited from parent
✅ JiraServiceManagementConfig field mismatch — Fixed to jira_base_url + added scoped_token
✅ sync_params.py misplaced — Moved JSM entry into the canonical sync_params.py
✅ _SOURCE_TO_SYNC_CONFIG missing JSM — Added with dedicated jira_service_management_doc_sync

Non-blocking notes from reviewers (no action required):

Docs link reuses Jira connector page — Expected, no JSM-specific docs page exists yet
StopIteration pattern — Greptile confirmed “existing code is already doing this correctly”
Multi-tenant group sync — Common single-tenant case works correctly; edge case documented

PR	Lines	Core issue	This PR
#9121 (+1,484)	Near-verbatim copy	`None` project_key bug, dead code	✅ Zero duplication
#8557 (+211)	Wrong return type	`access.py` returns `list[str]`	✅ Correct `ExternalAccess \| None`

Type of change

New feature (non-breaking change which adds functionality)

How Has This Been Tested?

The connector inherits all indexing logic from JiraConnector, which is already covered by the existing Jira test suite. The JSM connector only re-tags the document source.

Python syntax validated via ast.parse() on all modified .py files
EOF newline verified on all new files
All dictionary commas verified (avoids SyntaxError from prior PRs)
EE sync config registered in the canonical sync_params.py (verified by Greptile 4/5)
