Add Explicit "No Results Found" or "End of Matches" Message in PAW Rules/Process Editor Find Dialog

Dear team,

Idea Summary / Business Case:
When using Ctrl+F in the Rules Editor or TI Process Editor in PAW, if a search term yields no matches (or after cycling through all matches), no feedback is given. Users see only silent behavior (no highlight, no "Next" enabled), leading to confusion: "Is the term really not there? Did I miss something?" This wastes time, especially during debugging large rule sets or TI scripts.

Expected Benefit:
A simple message like "No results found" or "No more matches – reached end" provides immediate, clear feedback → improves user confidence, reduces trial-and-error, accelerates development.

Environment:
Planning Analytics versions: 2.0.x (v11) and 3.x (v12+)

Component: Planning Analytics Workspace – Rules Editor & Process Editor

Browsers: Chrome, Edge (tested)

OS: Windows, Linux

Steps to Reproduce:

1. Open Rules Editor or Process Editor in PAW.

2. Press Ctrl+F to open Find dialog.

3. Enter a non-existing term, e.g., "ThisStringDoesNotExistAnywhere".

4. Click "Find Next" repeatedly → No message; dialog stays unchanged/silent.

Actual Behavior:
No notification; user must infer "no results" from lack of action.

Expected Behavior:
Display a clear, non-intrusive message in/near the dialog, e.g.:

• "No results found" (for initial search)

• "No more matches" or "End of document reached" (after last match)

Similar to standard behavior in Notepad++, VS Code, or browser find (Ctrl+F).

This is a standard usability pattern missing in PAW editors – please prioritize for better developer experience.

With best regards,
Vitalij
