fix: resolve Invalid id in Terminal add in still installed error

[archiesaxenaa]

Root Cause

• DA projects return title IDs with T_ prefix (vs. U_ for traditional Office add-ins)
• Validation regex didn't recognize T_ prefix
• ATK CLI's atk uninstall --mode title-id doesn't support T_ IDs (30s timeout)

Solution

• Detect T_ prefix title IDs
• Strip the T_ prefix to extract the manifest GUID
• Use --mode manifest-id instead of --mode title-id for uninstall
• U_ IDs continue using --mode title-id (existing behavior)

Changes

• Modified uninstallWithTeams() in packages/office-addin-dev-settings/src/publish.ts
• Added separate regex patterns for T_ and U_ prefixes
• Auto-convert T_<guid> → --mode manifest-id --manifest-id <guid>

Validation/testing performed:

Local Testing done via npm link.
Stop command now works for DA projects without errors or timeouts. Clean add-in un-installation when office app is closed and debug is stopped.
