[BUG]: Stale workflow message does not match configured stale period

[MsParadox]

Bug Description

Bug Description

The stale workflow message does not match the configured stale period in .github/workflows/stale-manager.yml.

The workflow currently marks issues and pull requests as stale after 15 days:

days-before-stale: 15

But both stale messages say there has been no recent activity in the last 30 days.

This can confuse contributors because the automation behavior and the message shown by the bot are different.

Steps To Reproduce

1. Open .github/workflows/stale-manager.yml
2. Check the value of days-before-stale
3. Check stale-issue-message and stale-pr-message
4. Notice that the workflow uses 15 days, but the messages say 30 days

Expected Behavior

The stale workflow configuration and the stale messages should use the same number of days.

Maintainers can choose either:

• update the messages from 30 days to 15 days, or
• update the workflow setting from 15 days to 30 days

I would like to work on whichever fix the maintainers prefer.
