fix: cast string returns to int in MY_Migration (#4560)

basename() returns string and database column values are strings,
but get_latest_migration() and get_current_version() declare int
return types. PHP 8.0+ enforces strict return types and no longer
silently coerces strings to int, causing a TypeError on fresh
installs.

Fixes #4559

 ## Reporting a Vulnerability
 
-Please report (suspected) security vulnerabilities to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**. 
+**Option 1: GitHub Security Advisory (Preferred)**
 
-You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible depending on complexity but historically within a few days.
+1. Create a draft security advisory directly on GitHub:
+   - Go to https://github.com/opensourcepos/opensourcepos/security/advisories
+   - Click "New draft security advisory"
+   - Fill in the vulnerability details using our [template below](#vulnerability-template)
+   - Submit as **draft** (not published)
+
+2. Notify us for triage:
+   - Send an email to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)** with:
+     - Subject: `[GHSA] Brief description of vulnerability`
+     - Link to the draft advisory
+     - Brief summary
+
+**Option 2: Email Report**
+
+Send vulnerability details to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**.
+
+You will receive a response within 48 hours. Confirmed vulnerabilities will be patched within a few days depending on complexity.
+
+## Disclosure Process
+
+### Timeline
+
+| Step | Timeline | Action |
+|------|----------|--------|
+| 1. Report received | Day 0 | We acknowledge within 48 hours |
+| 2. Triage & confirmation | Day 1-3 | We validate the vulnerability |
+| 3. Fix development | Day 3-7 | We develop and test the fix |
+| 4. Patch release | Day 7-10 | We release a security patch |
+| 5. CVE request | Day 7-14 | We request CVE from GitHub (if applicable) |
+| 6. Advisory published | Day 14 | We publish the advisory with credit |
+| 7. Public disclosure | Day 14+ | Full disclosure after patch release |
+
+### CVE Process
+
+**We request CVE identifiers through GitHub's security advisory system.** This is the preferred and easiest method:
+
+1. After we confirm and fix the vulnerability, we'll request a CVE through GitHub
+2. GitHub coordinates with MITRE on our behalf
+3. The CVE is automatically linked to the advisory
+4. You'll be credited as the reporter in the published advisory
+
+**Already have a CVE?** If you've already obtained a CVE from another source (e.g., VulDB, CVE.MITRE.ORG), please include it in your report or advisory. We'll update our advisory to reference the existing CVE.
+
+### No Bug Bounty Program
+
+**Important:** Open Source Point of Sale does not offer a bug bounty program.
+
+- All security research and vulnerability triage is done on a **voluntary basis** in our free time
+- We do not offer monetary rewards for vulnerability reports
+- We do credit reporters in published advisories (unless anonymity is requested)
+- We greatly appreciate the security research community's efforts to help improve project security
+
+### Security Best Practices for Researchers
+
+- **Do not** access, modify, or delete data that doesn't belong to you
+- **Do not** perform denial of service attacks
+- **Do not** publicly disclose vulnerabilities before we've had time to fix them
+- **Do** provide sufficient information to reproduce the vulnerability
+- **Do** allow us reasonable time to fix before public disclosure
+- **Do** report through official channels (GitHub advisories or email)
+
+### Vulnerability Template
+
+When creating a draft advisory, please include:
+
+```

+- **Integrity:** [High/Medium/Low - what can be modified]
+- **Availability:** [High/Medium/Low - service disruption potential]
+- **Privilege Required:** [None/Low/High - authentication level needed]
+- **CVSS v3.1:** [Score] ([Vector string])
