feat(campaigns/templates): inline merchant logos via simple <img> sequence

The previous attempt (commit 3f72608) tried to inject a nested <table>
of logos, but the anchor selection logic looked for a </p> that didn't
exist — Unlayer renders the amount line inside a <div>, not <p>. As a
result the logos never made it into the templates.

This commit fixes it with a simpler approach: directly append the logo
images to the existing amount-text string. No table nesting, no anchor
hunting — just plain inline-block <img> tags right after the
"🎁 {{amount}} chez des centaines de marques" text.

Markup pattern (inserted right after the amount line, before the
closing </div>):

  <br><br>
  <span style="display:inline-block;">
    <img src="...amazon..." width="32" alt="Amazon" ...>
    <img src="...timhortons..." width="32" alt="Tim Hortons" ...>
    <img src="...walmart..." width="32" alt="Walmart" ...>
    <img src="...homedepot..." width="32" alt="Home Depot" ...>
    <img src="...iga..." width="32" alt="IGA" ...>
    <img src="...homehardware..." width="32" alt="Home Hardware" ...>
    <span style="font-size:13px;color:#64748B;">et plus</span>
  </span>

Each <img> uses display:inline-block + vertical-align:middle so they
sit on the same horizontal line. width=32 attribute set for Outlook;
height:auto in style preserves aspect ratio. margin-right:6px provides
spacing between logos. Caption ("et plus" / "and more") at the end.

Width math (inside 484px-wide pill): 6 × (32 + 6) = 228 px + caption
~50 px = 278 px. Fits with margin to spare.

EN translation auto-detected the equivalent anchor and inserted
"and more" instead of "et plus".

Live test-send verified for both FR + EN.
