Improve Outlook process detection for Cuda links

[fcilab2024]

Motivation

• Ensure the app reliably detects when a Cuda-protected link is launched from Outlook (both Classic and the new Outlook app on Windows 11) so the confirmation prompt is shown only when appropriate.
• Remove duplicated confirmation handling to avoid double logging and duplicate actions after the dialog.

Description

• Removed the duplicated dialog handling so the user confirmation is logged and acted on only once by keeping a single DialogResult branch.
• Replaced direct Process.GetProcessById(...).ProcessName usage with a snapshot-based lookup and added GetProcessNameById that reads names via Toolhelp (CreateToolhelp32Snapshot / Process32First / Process32Next).
• Updated IsCallerOutlook to use GetProcessNameById, fall back to a pid-<id> label when the name cannot be resolved, and log ancestor names consistently before checking IsOutlookProcessName.

Testing

• No automated tests were run for this change.
