[19.0][IMP] spreadsheet_dashboard_oca: manage dashboard share links

[volkantasci]

Following maintainer feedback, the share-link management feature previously proposed as the standalone spreadsheet_dashboard_share_oca module is now folded directly into the main spreadsheet_dashboard_oca module.

Core's spreadsheet_dashboard only lets users create share links; there is no UI to list or revoke them. This PR adds:

• a "Manage shares" entry on the dashboard Share button, opening a dialog to list, copy and revoke the share links of a dashboard;
• a badge next to the dashboard name in the sidebar showing the number of active shares;
• an ir.rule so spreadsheet_dashboard.group_dashboard_manager users can manage the shares created by any user (other users manage their own).

Python and JS tests moved along; module version bumped to 19.0.2.0.0.

Hi @pedrobaeza and @victoralmau 👋

Just a gentle check-in — if anyone has a moment, this PR would really benefit from a look whenever you're available. All CI checks are green (pre-commit, Odoo/OCB tests, codecov, runboat).

No pressure at all — happy to make any changes you suggest. Thanks for everything you do!

I think this should be part of the main module, as the share option is something already in it.

Hi @pedrobaeza, thanks for the feedback — and apologies for the slow reply.

Agreed, the share-link management UI belongs in the main module. To clarify what this PR adds: core's spreadsheet.dashboard.share only lets you create share links; there is no way in the UI to list existing links or revoke them. This PR fills that gap with a "Manage shares" dialog (list / copy / revoke) and a share-count badge — it builds on the existing share model, nothing is duplicated.

You're right that a separate companion module isn't the right shape for a small, dependency-free addition like this. We'll rework the PR to fold the feature directly into spreadsheet_dashboard_oca — model extensions, ir.rule, bundle patches and tests moved into the main module, retitled as [IMP] — and update it here. Thanks again for the direction!

Reworked as discussed, @pedrobaeza 👋

The PR no longer adds a standalone module — the share management is folded into spreadsheet_dashboard_oca itself:

• Manage shares dialog (list / copy / revoke) on the dashboard Share button,
• share-count badge next to the dashboard name in the sidebar,
• ir.rule for the dashboard manager group,
• Python + JS tests moved along, module version bumped to 19.0.2.0.0.

No new dependency is introduced. When you have a moment, could you take another look? Happy to adjust anything.
