* fix(security): Fix DOMPDF RCE and customer email sanitization
- Disable isPhpEnabled in DOMPDF to prevent RCE via embedded PHP in HTML
- Disable isRemoteEnabled to prevent SSRF attacks
- Add email validation and sanitization in CSV import (FILTER_SANITIZE_EMAIL, FILTER_VALIDATE_EMAIL)
- Reject invalid email formats during customer import
* fix(security): Escape email addresses in mailto() to prevent XSS
Email columns in bootstrap tables had escaping disabled (line 52) and
mailto() function doesn't escape its parameters. This fix escapes email
addresses before passing to mailto() in:
- get_person_data_row() (employees)
- get_customer_data_row() (customers)
- get_supplier_data_row() (suppliers)
Attack vector: Malicious email via CSV import renders XSS in table view.
* test(security): Add tests for customer CSV import email validation
Tests cover:
- Valid email acceptance
- Invalid email rejection with row-specific error
- XSS payload sanitization in email field
- Mixed valid/invalid email handling
- Email with special characters sanitization
Verifies fixes for customer email import vulnerability.
* fix(security): Allow empty email addresses in customer import
- Empty emails are now allowed (customers may not have email addresses)
- Validation only applies when email is non-empty
- Added test case for empty email acceptance
This fixes a regression where FILTER_VALIDATE_EMAIL rejected empty
strings, breaking imports for customers without email addresses.
