fix: position session action menu at touch/click point

- Updated useLongPress.ts to pass click coordinates to onLongPress callback
- Modified SessionList.tsx to use menuAnchorPoint state instead of menuAnchorRef
- Updated SessionActionMenu.tsx to position menu based on anchorPoint coordinates
- Enhanced SessionHeader.tsx to calculate anchorPoint from button position and added stopPropagation to fix toggle issue

The menu now appears at the exact touch/click position instead of being centered or aligned to the button edge.
