Documentation Issue: Outdated and Inconsistent Docs

## Description
While going through the **Flexprice documentation**, I noticed that it is highly inconsistent and difficult to follow. The documentation differs significantly from the actual product behavior and features.

Even worse, several provided **screenshots do not match the current UI/product**, which makes the docs misleading instead of helpful.

## Problem
- Large discrepancies between the documentation and the actual product.
- Screenshots are outdated and do not reflect the current state of the system.
- Release updates are not being reflected in the docs in a timely manner.
- As users, we are forced to compare with older versions or external references just to understand how things work now.

## Why This Matters
- New users (and even experienced ones) get confused and waste time figuring out what is correct.
- Documentation should be a source of truth, not a guessing game.
- Outdated docs increase onboarding time, cause errors, and lower confidence in the product.

## Suggested Solution
- **Update documentation alongside each product release** so it always reflects the latest state.
- Ensure that **screenshots and examples match the current UI and behavior**.
- Provide a **changelog or versioned documentation**, so users know what has changed without needing to infer it themselves.
- Consider adding a **"last updated"** tag or version label on each doc page.

## Impact
Clear, accurate, and up-to-date documentation will:
- Improve user adoption and trust.
- Reduce confusion and support requests.
- Allow teams to focus on using the product effectively rather than deciphering differences between docs and product.
