[19.0][ADD] base_tier_validation_correction: kanban view grouped by state

[bosd]

Draft — opened for discussion. Not for merge until the maintainers signal interest in a kanban view for this model.

Summary

Add a kanban view to tier.correction with default_group_by="state", giving a visual board view of the workflow:

draft -> prepare -> done -> cancel / revert

The kanban becomes the first view on the action so users land on the board when opening the menu (list and form still available).

Each card shows:

• the description (name) as the title,
• the target model_id as a subtitle,
• the creator avatar (many2one_avatar_user) in the top-right,
• the correction_type in the card body.

group_create="0" group_delete="0" so the fixed state Selection can't be turned into ad-hoc folders.

Why a draft

A kanban view is a real UI commitment: it's the entry point users will see first. Wanted to put it up for the maintainers to nod or push back on before polishing further (extra fields on the cards, decorations on the column titles, etc.).

Test plan

• Install / upgrade base_tier_validation_correction.
• Open Tier Review Correction menu: kanban opens by default, with columns for Draft / Preparing / Corrected / Cancelled / Reverted.
• Create one record of each state: each card appears in the right column with the model, correction type, and the creator avatar visible.
