fix: use infotip for help glyphs

[lyzno1]

Summary

• Replace question-mark help glyph Tooltip usages with Infotip across workflow, dataset, plugin, prompt, and model-provider UI surfaces.
• Keep status/action Tooltip usages intact, including the invited-modal error/status case.
• Update related tests for Infotip triggers and the added help button in subscription options.
