Add Check for IEC Standard Resistor on VtC

Some key notes:

En means that every decade (0.1-1.0, 1-10, 10-100, etc.) is divided in n steps on a logarithmic scale.

Series:

E6 - 20% tolerance E12 - 10% E24 - 5% (also available with 1%) E48 - 2% E96 - 1% E192 - 0.5% (also used for resistors with 0.25% and 0.1%).

The idea is that when a user has a value typed in, if it doesn't fall within its respective series, then we add a warning (new shade of gold is needed) to inform the user that this is not a standard IEC resistor

We will also likely add another link out to the standard resistor values page (not sure where yet).

Layout and Flow Idea:

• User Inputs Value → Types in resistance value and selects units and tolerance.
• "Validate Resistance Against E-Series" Button → User clicks on it.
  • If valid: A success message appears ("✅ Your value is part of the E-12 series").
  • If invalid: A warning appears with suggestions ("⚠️ Not in E-series, closest value is 22 kΩ").
• This validate button goes below all the dropdowns/text fields
• "Learn More about E-Series Standards" Button → Optionally, click to learn about E-series. Goes below the Validate button section
• Recommendation Action → "Use Closest Value" button for convenience if the value was not standard. - Likely a text button on a card that appears
• Add an animation for the card that display below the button

Observations: (10/10)

• [x] Second paragraph of app description needs to be updated for grammatical reasons.
• [x] When we use selected value the value should be an Int unless it needs to be a decimal
• [x] When we show recommended value we need to show it in the units that are selected in the dropdown (this makes it so we don't need to update the units dropdown)
• [x] Fix long decimals from floating point multiplication errors
• [ ] Clicking learn more and navigating back to the screen should keep the card visible

Observations (10/14):

• [ ] When clicking the button it doesn't clear focus on text field or drop downs
• [ ] When clicking on 0 and the unit isn't Ohms it'll say it's not standard with the recommended being 0 {units}, shows 0.1 only for Ohms
