Fix Google reviews avatars and add secondary “Laisser un avis” CTA

[CySSoO]

Motivation

• Improve avatar reliability and visual consistency so every review shows a circular, fixed-size avatar (image or initial) without layout regressions.
• Ensure reviewer header (avatar + name + date) stays on a single line and is vertically aligned.
• Add a clear, secondary CTA to let visitors leave a Google review from the block without changing schema or data.

Description

• Update views/templates/hook/_partials/google_reviews.tpl to add a secondary CTA under the primary button inside the left aside using btn btn-outline-secondary btn-sm that opens the existing cta_url in a new tab and is visually secondary to the main CTA.
• Adjust review header markup to use d-flex align-items-center gap-3 so avatar, name and date remain on one line across breakpoints.
• Ensure avatar containers include overflow-hidden rounded-circle and for image avatars replace rounded-circle on the img with w-100 h-100 object-fit-cover so photos fill the fixed 56px container without distortion or stretching, and add text-uppercase to fallback initials containers for consistent style.
• Add CSS rules in views/css/everblock.css for .everblock-google-reviews__avatar img to enforce width:100%, height:100% and object-fit: cover while keeping the fixed avatar size via the existing .everblock-google-reviews__avatar rule.

Testing

• No automated tests were executed for this change.
