fix(web): move {@const} blocks to immediate children of {#each}

Svelte 5 requires {@const} to be a direct child of certain blocks
({#snippet}, {#if}, {#each}, etc.). Placing them inside <li>
bodies broke the build with const_tag_invalid_placement. Moved
the RowAction const declarations up so they sit between {#each}
and the <li> opener; the each-binding (u/r) is in scope for the
entire each block body, so the consts behave identically.

Caught by local docker build on dev:
