Dynamic warranty link for manufacturers' support urls

[akemidx]

A way to dynamically produce a manufacturur's warranty link has been added.

Instead of building out code per individual manufacturer which is unscalable, this method will allow any manufacturer to have a warranty link be customized for use.

SupportURLs can now be written with {LOCALE} and {SERIAL} tags in them. Using these tags, the system will automatically replace {LOCALE} with the localization variable selected in settings. {SERIAL} will be replaced with the serial number of the asset being viewed.

For example:

-strict URL validation has been removed.
-urls must have :// in them to validate.
-Other special characters are now allowed as long as :// is in the link.
-No existing urls or presaved links should be affected, but will need to have :// if the manufacturer is edited in the future.
-urls are free to not use the tags
-the individual icons for manufacturers have been changed to a default "outside link" icon next to the warranty months

PR Summary

• Added SaveManufacturerRequest.php file
  A new file to handle saving manufacturer requests.
• Update support_url rule in Manufacturer model
  Changed the validation to use regex instead of only accepting URLs.
• Dynamic URL in AssetPresenter class
  The view method now returns a dynamic URL with serial number and locale for the manufacturer's support_url field, if it exists. Otherwise, it returns false (as before).
• Improved support URL handling in hardware/view template
  Replaced manufacturer-specific icons with a generic external link icon, and the link will directly point to the URL generated by $asset->present()->supportUrl(). This adds flexibility for adding new manufacturers and allows users to use custom URLs for warranty lookup without relying on external sites.

Additionally, a byproduct of this change will open up the support url field to be used for more diverse links/clickthroughs rather than strict web urls

We probably don't want to leave a dd() in there

[snipe]

As I mentioned on the dev call, we might be able to simplify this a bit, using the starts_with validation.

'support_url' => 'nullable|starts_with:http://,https://',afp://,facetime://,file://,irc://'

[snipe]

This looks really good - just a few changes!

[snipe]

Do we need to use brackets here? I don't think we do - just

'support_url' => 'nullable|starts_with:http://,https://,afp://,facetime://,file://,irc://',

should do it, no? I'd prefer that for consistency if it works.

all set

I don't think we need this anymore?
