Add #{job_id} as a substitutable parameter in the Execute Service

[Copilot]

The Execute Service's parameter substitution had no way to reference the current job ID in command arguments. This adds #{job_id} as a built-in placeholder available in both Execute Once and Execute Many operations.

Changes

• ExecuteService API — adds JOB_ID_PATTERN = "#{job_id}" constant alongside the existing pattern constants
• ExecuteServiceImpl.doProcess(MediaPackage) — adds #{job_id} as a case in the regex-based matcher loop, alongside the existing id, org_id, out, flavor, and tags cases. Job is passed as a new parameter.
• ExecuteServiceImpl.doProcess(MediaPackageElement) — adds #{job_id} as a pattern-replacement check in the per-argument loop, alongside the existing #{in}, #{out}, #{id}, and #{org_id} replacements. Job is passed as a new parameter.
• execute.md — documents #{job_id} in the parameter substitution table as available in both Execute Once and Execute Many
• ExecuteServiceImplTest — adds testWithJobIdParam exercising the substitution through doProcess() directly with a mocked Job

Usage

operation: execute-once
exec: my-script
params: --job-id #{job_id} --mediapackage #{id}

The execute service workflow operation handler is defined in https://github.com/cilt-uct/opencast/tree/6ddbe89ba0128819e18d71e90edca9e5ba97619d/modules/execute-impl

Parameters that can be substituted on the command line are described at https://docs.opencast.org/r/19.x/admin/#configuration/execute/#parameter-substitution

Add the workflow job id as a substitutable parameter with the ID #{job_id}

Create a pull request to modify the execute WOH code to add this, and update the documentation https://github.com/cilt-uct/opencast/blob/6ddbe89ba0128819e18d71e90edca9e5ba97619d/docs/guides/admin/docs/configuration/execute.md#parameter-substitution

@copilot For consistency with how the other parameters are handled, move this code to inside doProcess() and pass the job as a parameter to doProcess() so that the job id is available there.

Done in 007088b. Moved the #{job_id} substitution into both doProcess() methods with Job as a new parameter:

• In doProcess(MediaPackage): added as a regex matcher case alongside id, org_id, etc.
• In doProcess(MediaPackageElement): added as a pattern-replacement check alongside #{in}, #{out}, #{id}, #{org_id}

@npmali Please checkout and test this branch on devubuopc003 / mediadev with a test workflow to confirm that the #{job_id} parameter substitution works in the execute service.
