The Sign app now uses a lighter signature capture tool that does not rely on jQuery. This reduces dependencies and helps prepare the product for future frontend modernization while keeping signing flows working as expected.

The jSignature library depends on jQuery. As we plan to remove jQuery in
the future, jSignature is replaced by another (simpler) library,
with fewer dependencies.

Enters signature_pad [1], which looks well maintained, has no external
dependency and is (roughly) 1/3 of the size.

This commit adapts the related components.

This update adds database indexes to the analytic plan columns to speed up searches when working with large datasets. This improvement makes operations like deleting accounts faster and more efficient, especially when the system has many analytic items linked together.

The table linked to analytic items can be pretty huge, and searching by account needs to be fast.
For instance, this index can be used when deleting an account because of the foreign keys.

This change reorders the website sitemap to list manually created pages before system controllers. Pages are typically more important content that users intentionally create, are updated more frequently, and are fewer in number than controllers. This ordering may help search engines prioritize crawling your most important content, especially if they have limited crawling budgets for large websites.

This shouldn't change anything regarding SEO, but is worth a try.
It will also impact the link suggestion when creating a link in the
editor, but having pages listed first also have sense there, or at least
it won't be worst.

The idea for the SEO part is that if the sitemap order (if too long)
would have some impact as crawlers might have a limited crawling budget
for your website and it will only crawl the first pages it finds.
Are those "first pages" impacted by the sitemap order? It's almost sure
it's not, as Google definitely knows how to crawl on its own, and is
even probably ignoring the sitemap most of the time.

Also, pages:
- Are probably always important content since you created manually a page to
  write something, while (some) controllers might just be content you
  care less about. Pages are probably always important while we can't
  say that for controllers.
- Should be fewer in number than controllers most of the time
- Have a lastmod set, as opposed to controllers

For all those reasons, this commit reverse the pages vs controllers
order in the sitemap.

This is coming from our prod where some pages are yet not indexed while
they have been published months ago.
