[18.0][ADD] web_widget_mapbox: Mapbox map form widget

[ivs-cetmix]

Summary

• Add a Community form widget (widget="mapbox" on fields.Json) that renders markers from a JSON payload with Mapbox GL JS loaded from the CDN (v3.30.0), not vendored.
• Store a dedicated Settings token (web_widget_mapbox.token / session mapbox_token) so this addon can sit next to Enterprise web_map without sharing map_box_token.
• Support computed non-stored JSON for display, optional marker drag into updated, Map/Satellite styles, zoom/pan/pitch/ fullscreen flags, and a popup form when clickable + rec_model + rec_id are set.

Test plan

• Install web_widget_mapbox on Community 18.0.
• Set Settings → General Settings → Integrations → Mapbox Token to a public pk. token and save.
• Put <field name="…" widget="mapbox"/> on a Json field and confirm the map renders; computed non-stored Json still displays.
• Check camera uses default_center when valid, else the first pin; zoom/pan/pitch/fullscreen follow allow_*.
• Drag an editable marker and confirm updated is upserted without rewriting elements.
• Click a marker with clickable + rec_model + rec_id and confirm a form dialog opens (not the main action stack).
• Confirm a portal session does not receive mapbox_token.

NB: this code was written using AI-assistance (Cursor), however was checked manually from A to Z. Yup, AI is a reality, just need to keep it under control 😄

Hey @etobella @rvalyi @pedrobaeza I know this is not in the /web repo, yet it's a widget, so it might deserve your attention 😄

If it doesn't depend on anything of geoengine as I see in the manifest, it should go to OCA/web.

@pedrobaeza
Yes, I thought about it as well. However it's about maps and geo things, and this is the first repo where functional people would be looking for a module like this.
Same did I before pushing it.

Can you include some kind of demo views to try the module?

This will require to add some models as well. However I can do a tiny web_widget_mapbox_demo module, let me know this wokrs for you.

[pedrobaeza]

I was thinking in doing it in res.partner module, as it's in base one, and add menu/view in demo data as well. Isn't that enough, or do you need some fields? If not, a demo module may serve.

[ivs-cetmix]

Yup, I thought about base and res.partner first as well, however we need some fields to store coordinates. Let me check what's would be the best solution here.
