Fix home carousel id assignment

[CySSoO]

Motivation

• Prevent generating the carousel DOM id inside the Smarty template to avoid template-side uniqid usage and potential caching/duplicate id issues.
• Ensure a single unique id is produced on the PHP side so templates can rely on a precomputed value.
• Make the hook output deterministic for cached templates by computing the id before assigning Smarty variables.

Description

• Generate the carousel id in hookDisplayHome with $carouselId = 'everpsblog-home-slider-' . uniqid('', true); and assign it to Smarty as carousel_id in everpsblog.php.
• Remove the Smarty-side {assign var=carousel_id value='everpsblog-home-slider-'|cat:uniqid()} from views/templates/hook/home.tpl and use the assigned {$carousel_id} directly.
• Updated files: everpsblog.php and views/templates/hook/home.tpl to centralize id generation in PHP.

Testing

• No automated tests were executed for this change.
• Changes were committed and both modified files were staged and recorded in a commit titled Fix home carousel id assignment.
