Allow selecting between Bootstrap 5 and TailwindCSS on first setup of vlsuite utility submodule

Ready to review:
On a fresh installation:

• Just access to /admin/config/vlsuite/utility-classes
• Configure the framework
  
• If it selects Bootstrap or Tailwind, it will load default utility classes
• If it selects Custom, it will load the same utility classes as Bootstrap but empty, so each utility class will need to be filled or removed.
• If the site already has configuration, the form will set bootstrap5 as the default framework

Added testing coverage, ready to review

Thanks Edu, looks good.

On a fresh install tested that utilities were applying on both TailwindCSS 4 and Bootstrap 5. However some of the TailwindCSS utilities are not correct.

On the custom theme option we will keep only the following utilities as a base:

buttons
badge
text-align
text-color
bg-color
spacing
spacing-y
spacing-x
headings
font-size
font-family

We maintained the following list as the following attributes were not on the module:

spacing
spacing-y
spacing-x
headings
font-size
font-family

• text-align
  • left
  • right
  • center
• color
  • primary
  • secondary
• background-color
  • primary
  • secondary
• btn
  • primary
  • secondary
  • success
  • info
  • warning
  • danger
• btn-size
  • large
  • small

Tested with a custom theme based on TailwindCSS. Utility classes are applied correctly, and behavior is consistent with what is expected.

Fixed!
