Floxis Bid Adapter: initial release (#13934)

* Floxis Bid Adapter : initial release

* Added ORTB parameters for blocking

* Adjusted documentation with maintainer info

* Added more validations, extracted converter to a const

* Floxis Bid Adapter: redesign to seat-based architecture with ortbConverter

Major rewrite replacing teqblazeUtils with ortbConverter for ORTB 2.x compliance.

Changes:
- New params: seat (required), region (required), partner (required)
- Endpoint URL: https://{subdomain}.floxis.tech/pbjs?seat={seat}
  - subdomain = region for 'floxis' partner
  - subdomain = {partner}-{region} for white-label partners
- ORTB-native implementation with Floors Module support
- 40 comprehensive tests with full code coverage
- Updated documentation with examples

Addresses all PR #13934 review comments from @osazos

* Rename FloxisBidAdapter.md to floxisBidAdapter.md

* Code review adjustments

+# Overview
+
+```
+Module Name: Floxis Bidder Adapter
+Module Type: Bidder Adapter
+Maintainer: admin@floxis.tech
+```
+
+# Description
+
+The Floxis Bid Adapter enables integration with the Floxis programmatic advertising platform via Prebid.js. It supports banner, video (instream and outstream), and native formats.
+
+**Key Features:**
+- Banner, Video and Native ad support
+- OpenRTB 2.x compliant
+- Privacy regulation compliance (GDPR, USP, GPP, COPPA)
+- Prebid.js Floors Module support
+
+## Supported Media Types
+- Banner
+- Video
+- Native
+
+## Floors Module Support
+The Floxis Bid Adapter supports the Prebid.js [Floors Module](https://docs.prebid.org/dev-docs/modules/floors.html). Floor values are automatically included in the OpenRTB request as `imp.bidfloor` and `imp.bidfloorcur`.
+
+## Privacy
+Privacy fields (GDPR, USP, GPP, COPPA) are handled by Prebid.js core and automatically included in the OpenRTB request.
+
+## Example Usage
+```javascript
+pbjs.addAdUnits([
+  {
+    code: 'adunit-1',
+    mediaTypes: { banner: { sizes: [[300, 250]] } },
+    bids: [{
+      bidder: 'floxis',
+      params: {
+        seat: 'testSeat',
+        region: 'us-e',
+        partner: 'floxis'
+      }
+    }]
+  }
+]);
+```
+
+# Configuration
+
+## Parameters
+
+| Name | Scope | Description | Example | Type |
+| --- | --- | --- | --- | --- |
+| `seat` | required | Seat identifier | `'testSeat'` | `string` |
+| `region` | required | Region identifier for routing | `'us-e'` | `string` |
+| `partner` | required | Partner identifier | `'floxis'` | `string` |
+
+## Testing
+Unit tests are provided in `test/spec/modules/floxisBidAdapter_spec.js` and cover validation, request building, response interpretation, and bid-won notifications.
