18.0 Add DMS workspace UI

[windweaver828]

Summary

This PR adds dms_workspace_ui, an optional modern workspace interface for OCA DMS.

The addon keeps the existing DMS models, permissions, routes, menus, and classic views intact. It adds a new workspace-style Documents action with:

• card/grid file browsing
• persistent folder tree/sidebar
• file/folder selection
• context menu actions
• inspector/details panel
• upload/new folder/rename/delete flows
• responsive layout support

The goal is to improve first-use usability of OCA DMS without replacing or rewriting the existing backend behavior.

Scope

This PR only adds the optional dms_workspace_ui addon.

It does not:

• change DMS models
• change DMS security
• change existing DMS routes
• remove existing DMS views

Validation

Locally validated with:

• Python compile checks
• XML parse checks
• Odoo module install/update
• Manual checks for behavior such as folder navigation, file selection, context menu, dialogs, upload cancel, archive/restore, and responsive layout

Notes

The addon is new UI surface area, and I’d appreciate maintainer feedback on naming, placement, and whether this belongs in OCA/dms as an optional addon. Any feedback is taken to heart and greatly appreciated. Thank you.

Installing the addon hides the original DMS Files/Directories and DMS Field Documents pages by default, toggleable in the general settings of the app.

Also not seen, keyboard navigation is included.

• Tab swaps between filetree and files pane.
• Typeahead jumping, type and it jumps to matching locations
• Arrow keys navigate
• Ctrl + Left click multi selects
• Spacebar also multi selects
• Shift + Arrow keys also multi selects
• Alt hotkeys overlay works with Add File and New Folder buttons
• In filetree Left/Right arrow and Spacebar expands/collapses folders
• Delete key to delete
• F2 for rename

Extras seen in pictures that are not included

• description preview (there is a PR with this required addon at [18.0][ADD] dms_file_description: add descriptions to DMS files #481)
• OnlyOffice integration (PR coming soon!)
  Also of note, both of those PRs work with regulard dms also, this is not required for them to work.
