Fix XSS vulnerabilities in sales templates, login, and config pages

This commit addresses 5 XSS vulnerabilities by adding proper escaping
to all user-controlled configuration values in HTML contexts.

Fixed Files:
- app/Views/sales/invoice.php: Escaped company_logo (URL context) and company (HTML)
- app/Views/sales/work_order.php: Escaped company_logo (URL context)
- app/Views/sales/receipt_email.php: Added file path validation and escaping for logo
- app/Views/login.php: Escaped all config values in title, logo src, and alt
- app/Views/configs/info_config.php: Escaped company_logo (URL context)

Security Impact:
- Prevents stored XSS attacks if configuration is compromised
- Defense-in-depth principle applied to administrative interfaces
- Follows OWASP best practices for output encoding

Testing:
- Verified no script execution with XSS payloads in config values
- Confirmed proper escaping in HTML, URL, and file contexts
- All templates render correctly with valid configuration

Severity: High (4 files), Medium-High (1 file)
CVSS Score: ~6.1
CWE: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Fix critical password validation bypass and add unit tests

This commit addresses a critical security vulnerability where the password
minimum length check was performed on the HASHED password (always 60
characters for bcrypt) instead of the actual password before hashing.

Vulnerability Details:
- Original code: strlen($employee_data['password']) >= 8
- This compared the hash length (always 60) instead of raw password
- Impact: Users could set 1-character passwords like "a"
- Severity: Critical (enables brute force attacks on weak passwords)
- CVE-like issue: CWE-307 (Improper Restriction of Excessive Authentication Attempts)

Fix Applied:
- Validate password length BEFORE hashing
- Clear error message when password is too short
- Added unit tests to verify minimum length enforcement
- Regression test to prevent future vulnerability re-introduction

Test Coverage:
- testPasswordMinLength_Rejects7Characters: Verify 7 chars rejected
- testPasswordMinLength_Accepts8Characters: Verify 8 chars accepted
- testPasswordMinLength_RejectsEmptyString: Verify empty rejected
- testPasswordMinLength_RejectsWhitespaceOnly: Verify whitespace rejected
- testPasswordMinLength_AcceptsSpecialCharacters: Verify special chars OK
- testPasswordMinLength_RejectsPreviousBehavior: Regression test for bug

Files Modified:
- app/Controllers/Home.php: Fixed password validation logic
- tests/Controllers/HomeTest.php: Added comprehensive unit tests

Security Impact:
- Enforces 8-character minimum password policy
- Prevents extremely weak passwords that facilitate brute-force attacks
- Critical for credential security and user account protection

Breaking Changes:
- Users with passwords < 8 characters will need to reset their password
- This is the intended security improvement

Severity: Critical
CVSS Score: ~7.5
CWE: CWE-305 (Authentication Bypass by Primary Weakness), CWE-307

Add GitHub Actions workflow to run PHPUnit tests

Move business logic from views to controllers for better separation of concerns

- Move logo URL computation from info_config view to Config::getIndex()
- Move image base64 encoding from receipt_email view to Sales controller
- Improves separation of concerns by keeping business logic in controllers
- Simplifies view templates to only handle presentation

Fix XSS vulnerabilities in report views - escape user-controllable summary data and labels

Fix base64 encoding URL issue in delete payment - properly URL encode base64 string

Fix remaining return type declarations for Sales controller

Fixed additional methods that call _reload():
- postAdd() - returns _reload($data)
- postAddPayment() - returns _reload($data)
- postEditItem() - returns _reload($data)
- postSuspend() - returns _reload($data)
- postSetPaymentType() - returns _reload()

All methods now return ResponseInterface|string to match _reload() signature.
This resolves PHP TypeError errors.
