chore(release): 1.5.1

[ifahimreza]

Release 1.5.1, on Fahim's "saddle 1.5.1 release then".

What

• Version 1.5.1 in all five places: plugin header, SADDLE_VERSION, readme Stable tag, package.json, package-lock.json.
• Changelog: the one-page layout (A module can be one page, with no sidebar (#330) #331, already written) and the white sidebar panel (Module sidebar: a white panel beside left-aligned content #329, new line).
• languages/saddle.pot regenerated: the same 2,156 strings, new version header and line numbers.

Why

Saddle Analytics now draws one page with no sidebar, but only on a Core that knows 'layout' => 'page'. WordPress.org serves 1.5.0, so every site shows Analytics with a sidebar until this ships.

Not in this release

#323 (admin polish from the 1.5.0 QA) is a long list and S7 needs a mockup first. It moves to the next release.

Testing

• CI green on main 88dfe95 (composer lint, composer test)
• npm run test:js 342/342, npm run lint:js clean
• npm run build reproduces the committed admin/build byte for byte (node 26)
• npx grunt build: saddle-1.5.1.zip, 296 files; no updater, no includes/lib, no tests, no .md, no class-saddle-ecosystem.php; versions 1.5.1 in the zip; no exec-family calls (the grep hits are the word "system" in prose), no file writes, outbound only in the five known classes
• Plugin Check 2.1.0 by path on the extracted zip: 0 errors, the same 4 known warnings (readme name, one adapter hook name, two dynamic hooks)
• Live on saddle.site (WordPress 7.1.2, Core main): Analytics draws one page with no sidebar; SEO keeps the white panel
• The safety checklist (read tier default, gate, trash, connect/revoke) was not re-run: no PHP in those paths changed since 1.5.0

After merge

Tag v1.5.1 on main. release.yml checks the versions, builds the zip, publishes the GitHub Release and pushes to WordPress.org SVN.
