[feat] Add tooltip support for Vue nodes (#5577)

## Summary

Added tooltip support for Vue node components using PrimeVue's v-tooltip
directive with proper data integration and container scoping.


https://github.com/user-attachments/assets/d1af31e6-ef6a-4df8-8de4-5098aa4490a1

## Changes

- **What**: Implemented tooltip functionality for Vue node headers,
input/output slots, and widgets using [PrimeVue
v-tooltip](https://primevue.org/tooltip/) directive
- **Dependencies**: Leverages existing PrimeVue tooltip system, no new
dependencies

## Review Focus

Container scoping implementation via provide/inject pattern for tooltip
positioning, proper TypeScript interfaces eliminating `as any` casts,
and integration with existing settings store for tooltip delays and
enable/disable functionality.
