Incorrect "Bad value" warning for dynamically assigned variable

### Apache NetBeans version

Apache NetBeans 18

### What happened

On this line
```xml


```
the IDE flags

```
Bad value " " for attribute "value on element 'input": Expected a minus sign or a digit but saw " instead " for attribute "value" on element "input": Expected a minus sign or a digit but saw "
From line 68, column 9; to line 68, column 119
(Rule Category: Attributes)

```

As the value of $_SESSION['stock']['action_price'] is dynamically set during runtime and the IDE cannot determine its actual value, it should not report an error - which causes the programmer to think that the syntax is wrong.

I wasn't able to resolve this even with chatGPT :) which suggested to ignore the warning (provided that at runtime the type checks are ok).

Still the warning is annoying.

Start by reproducing the warning in the PHP/HTML input example from the issue using Apache NetBeans 18. The payload names no source files or tests, so locate the HTML attribute validation entry point and its related tests first. Done means dynamically assigned PHP values no longer produce an incorrect numeric-value warning while genuine invalid values remain reported.
