Fix ProcessFileJobTest by removing deprecated OCP\Snowflake\IGenerator dependency

[Copilot]

The test fails because OCP\Snowflake\IGenerator was removed from Nextcloud. The JobList constructor no longer requires this parameter.

Changes:

• Replace concrete OC\BackgroundJob\JobList with OCP\BackgroundJob\IJobList interface
• Remove IGenerator mock and property
• Simplify test setup: $this->jobList = $this->createMock(IJobList::class)
• Remove obsolete database and query builder mocks

Before:

$this->generator = $this->createMock(IGenerator::class);
$this->jobList = new JobList(
    $connectionMock,
    $configMock,
    $timeFactoryMock,
    $this->logger,
    $this->generator
);

After:

$this->jobList = $this->createMock(IJobList::class);

Aligns with current Nextcloud server test patterns.
