* feat: group backlinks table by domain with expandable rows
Group individual backlinks by source domain in the Backlinks tab,
showing a compact domain summary row that expands to reveal individual
backlink entries. Uses TanStack Table for expand/collapse state
management with table-fixed layout for stable column widths.
* fix: ci:check fixes for grouped backlinks table
Extract BacklinkChildRow to its own file to stay under max-lines lint
rule. Remove unused export of sortBacklinkRows. Format files with
prettier.
* refactor: simplify grouped backlinks table
* refactor: split backlinks page tables into focused files
Break the backlinks, referring domains, and top pages tables into dedicated components so the feature stays easier to navigate and no longer needs a max-lines ignore.
* fix: correct grouped backlink totals and remove target sorting
* fix: stabilize backlinks table column layout
Keep the DA header aligned with numeric cells and lock the backlinks table to fixed column widths so expanded rows with long anchor text do not shift the layout.
* refactor: inline backlinks table imports
