feat(applications): support plugin tools and instrument windows

[PierreRaybaut]

Follows #22 (merged).

DataLab-Web now supports the plugin tools of DataLab-Platform/DataLab#384, including instruments:

• The host shim gains verbatim copies of datalab.plugin_tools, plugin_instruments and plugin_resources. dlw_plugins validates tools at activation and reports them in the plugin payload. dlw_applications launches tools and opens, previews and acquires instruments; acquisitions are added in a new group, with rollback on failure.
• Tools are listed in the plugin's submenu of the Plugins menu of their panel, and in a Tools section of the Applications window, which now also lists tools-only plugins. Entries are disabled when the selection does not match, and the button tooltip tells what to select.
• New floating instrument window: live view on the left (curves with a fixed Y range, or an image with a fixed color range), auto-generated settings on the right with live active states, Live and Acquire buttons. Acquired objects are selected, and the Applications window assesses the methods on them.
• The bundled Camera and Pulse wheels are rebuilt from feat: add a scientific camera simulator tool datalab-camera-characterization#2 and feat: add an oscilloscope simulator tool datalab-pulse-characterization#2, which add a scientific camera simulator and an oscilloscope simulator.
• Separate fix: in parameter forms, a checkbox that has only its own text no longer shows its internal field name as a label, as in DataLab Desktop.

Tests

• Vitest: 745 passed (new tests for tool actions, the Tools section, the instrument window and the checkbox label); pytest: 362 passed, plus 17 Camera and Pulse application tests with the two simulators. Prettier, ESLint, tsc and i18n:check pass.
• Playwright: 19 application, plugin and bundle specs pass, including the new instrument_tools.spec.ts: the oscilloscope pulse pair and the camera exposure sequence are previewed, acquired, and make the two-channel delay and photon transfer methods ready.

Docs: doc/plugins.md gets a "Tools and instruments" subsection; CHANGELOG updated; 20 French translations added.
