**Small Security Issue:** CSV exports were vulnerable to formula
injection attacks when users entered values starting with =, +, -, or @.
(only happens if a logged-in user injects corrupted data)
Solution:
- Added ZWJ (Zero-Width Joiner) protection that prefixes dangerous
values with invisible Unicode character
- This is the best way to preserve original data while preventing Excel
from executing formulas
- Added import cleanup to restore original values when re-importing
Changes:
- New sanitizeValueForCSVExport() function for security
- Updated all CSV export paths to use both security + formatting
functions
- Added comprehensive tests covering attack vectors and international
characters
- Also added cursor rules for better code consistency

After moving a section on the frontend, this broke the path that was
sent by email on the backend.
This kind of error comes back every ~2-3 month under different forms so
we need a more robust solution: I moved routes to the shared folder,
that way we will share one common source of truth between the frontend
and the backend.
Fixes#14343
