refactor: Standardize DOM element dataset attributes across file browser component

[AuDevTist1C]

Summary

This pull request standardizes DOM element attribute naming across the file browser component by converting legacy custom attributes to standard HTML5 data-* dataset attributes.

Previously, template elements mixed standard properties with proprietary DOM attributes (such as action, type, name, home, open-doc, ftp-account, uuid, and storageType). This PR updates the component to use standard data-* markup, native dataset JavaScript accessors, and compliant CSS selectors.

Key Changes

1. Template Refactoring (src/pages/fileBrowser/list.hbs)

• Converted legacy inline attributes to standard data-* dataset equivalents (data-action, data-type, data-name, data-home, data-open-doc, data-ftp-account, data-uuid, and data-storage-type).
• Updated template conditionals to align with boolean and string dataset values (openDoc, ftpAccount).

2. Script Adaptations (src/pages/fileBrowser/fileBrowser.js)

• Refactored event delegation and element lookup handlers to utilize standard camelCase JavaScript dataset properties (e.g., replacing el.getAttribute('open-doc') with el.dataset.openDoc, along with dataset.action, dataset.uuid, dataset.type, and dataset.storageType).
• Updated action routing logic to handle openDoc dataset values.
• Replaced attr-action="navigation" with data-action="navigation" in dynamically generated navigation tags.

3. Stylesheet Selectors (src/pages/fileBrowser/fileBrowser.scss)

• Updated CSS attribute selectors from [storageType="notification"] to [data-storage-type="notification"].
• Updated pseudo-element content CSS function from attr(storageType) to attr(data-storage-type).

Benefits

• HTML Compliance: Eliminates non-standard, invalid DOM attributes.
• Performance & Cleanliness: Avoids verbose getAttribute() / setAttribute() DOM calls in favor of direct dataset accessors.
• Future-Proofing: Minimizes the risk of attribute name collisions with future HTML specifications.

Greptile Summary

Standardizes file-browser DOM metadata on HTML5 data-* attributes.

• Updates list-item templates and dynamically generated breadcrumbs to emit dataset-compatible attributes.
• Updates delegated click handling to read the corresponding camel-cased dataset properties.
• Aligns storage-type CSS selectors and generated content with the new markup.

Confidence Score: 5/5

The PR appears safe to merge, with the template producers, dataset consumers, dynamic navigation markup, and CSS selectors aligned.

The changed list-rendering and open-document paths consistently emit and consume the same dataset keys, and no reachable behavioral, styling, or security failure remains.

Important Files Changed

Filename	Overview
src/pages/fileBrowser/fileBrowser.js	Migrates file-browser event metadata access and generated navigation markup to consistent dataset properties without an identified behavioral regression.
src/pages/fileBrowser/list.hbs	Migrates list-item metadata to data attributes while keeping the open-document producer, template key, and event consumer aligned.
src/pages/fileBrowser/fileBrowser.scss	Updates storage-type selectors and pseudo-element content to match the renamed data attribute.
