fix reject liinks (#272)

Dear team,

This PR addresses a bug related to the idCampaign variable and the
assignment of the idLink variable. The following changes have been made
to resolve the issues:

Fixing idCampaign Bug: The bug in the idCampaign variable has been
resolved

Assigning idLink from URL Parameter: The idLink variable is now assigned
the value of req.params.id, which retrieves the parameter from the
request URL. This ensures that the correct idLink is obtained for
further processing within the function.

These changes aim to fix the bugs and ensure that the correct values are
used for idCampaign and idLink in the rejectLink function. Reviewers,
please verify the updated code and provide any feedback, suggestions, or
alternative approaches if necessary.

Thank you for your attention to detail and your valuable input.

Best regards,
Rania Morheg
