feat(jira): expose DevLake project name as ExtraJQL template variable

Users often want to filter a shared Jira board per Devlake project using the devlake project name.  The ExtraJQL field supports Go text/templates, but only BoardId and BoardName are available.

Look up the Devlake project name from the project_mapping table at task setup time and expose it as {{.ProjectName}} in ExtraJQL templates.

Example scope config ExtraJQL:
component = {{.ProjectName}}
