fix: Remove explicit parameter names from @PathVariable annotations

- Change @PathVariable("agentId") to @PathVariable for agentId parameters
- Change @PathVariable("threadId") to @PathVariable for threadId parameter
- Follow established pattern from TicketTaskController.java
- Addresses SonarCloud java:S6856 rule violations for @PathVariable binding
