fix(replication): support positional log arguments

[rambhardwajj]

Description

This pull request fixes the replication log command by allowing positional EXECUTION_ID and TASK_ID arguments as documented.

Previously, the command rejected positional arguments due to incorrect Cobra validation (MaximumNArgs(0)), creating a mismatch between the CLI behavior and its documentation.

• Fixes [bug]: replication log rejects advertised positional execution and task IDs #939

Type of Change

• Bug fix
• New feature
• Refactor
• Documentation update
• Chore / maintenance

Changes

• Updated harbor replication log to accept the advertised positional EXECUTION_ID and TASK_ID arguments.
• Added validation for invalid positional IDs and conflicts when IDs are provided both as flags and arguments.
• Added focused tests for replication log positional argument handling.
• Regenerated CLI Markdown and man page documentation with Dagger.

Thank you for spotting the inconsistency in the usage docs. Instead of changing this much code please just change Use: "log [EXECUTION_ID] [TASK_ID]" since those are treated through flags. Minimal changes are always preferred and would not change already existing behavior.

Please just update docs
