fix: name the WooCommerce integration row (#146)

[ifahimreza]

Closes #146

What

Adds a WooCommerce display entry to KNOWN in the Integrations screen, and regenerates languages/saddle.pot.

Why

Saddle Pro's saddle_integration_ui_prefixes hook contributes four detection-gated prefixes, not three — yoast- (7 tools), rank-math- (5), aioseo- (3) and wc- (9). #144 gave display entries to the three SEO ones and missed the store, so on a Pro + WooCommerce site the "Detected integrations" panel rendered a row titled literally wc with an empty description, via detectIntegrations()'s { title: key, description: '' } fallback. Same symptom class as the rank row #143 fixed, reached through the missing-entry path rather than the prefix split.

How

• wc-check-setup splits to two === 'wc-check', which isn't in KNOWN, so parts[0] → wc is the key registered. The two-segment prefix logic needed no change.
• Honesty of the panel is unchanged and still enforced on the Pro side: saddle_pro_integration_ui_prefixes() only pushes wc- while Saddle_Pro_WC::is_active(), so no WooCommerce, no row.
• The .pot was last generated 2026-08-21 and so was stale by fix: display the native Pro SEO integrations on the Integrations screen (#143) #144's six SEO msgids as well as these two. Regenerated with the same toolchain the header records (WP-CLI 2.12.0); the diff is purely additive — eight new msgids, zero removals, no header or version change.

Testing

• npm run lint:js — clean
• npm run build — bundle rebuilt, tracked output committed; only the pre-existing bundle-size warnings
• .pot regeneration verified reproducible: regenerating against the pre-change tree reproduces the committed file byte-for-byte apart from POT-Creation-Date, so the exclude list is the one that produced it
• Not exercised against a live Pro + WooCommerce install — verified by reading the wiring on both sides (saddle-pro.php:313 → class-saddle-rest.php:937 → Integrations.jsx)

No PHP changed. The repo's PHPUnit suite currently fails on main for an unrelated reason (build-page playbook text assertion, 612 tests / 1 failure); this branch does not affect it.
