fix(plating-perms): address final-reviewer critical + important issues

Pre-deploy fixes for Phase 1 permissions overhaul branch (catches by
final-reviewer subagent + main session).

CRITICAL FIXES:

C1: groups_id -> group_ids (Odoo 19 field rename). Affected ~30 sites
    across 4 model files, 1 view, 7 test files. Documented project
    gotcha (feedback_odoo19_groups_id_renamed.md) that the implementer
    subagents missed because they don't see user memory.

C2: action_fp_resolve_plating_landing server action now calls
    env['ir.actions.act_window'].sudo()._fp_resolve_landing_for_current_user()
    instead of the old inline priority chain. Phase E's role-based
    dispatch was previously dead code.

C3: New migrations/19.0.21.1.0/post-migrate.py triggers
    _fp_post_init_role_migration(env) on -u. post_init_hook only fires
    on INSTALL in Odoo 19, not UPGRADE -- so Phase H's preview creation
    wouldn't have auto-fired on entech without this script. Module
    version bumped to 19.0.21.1.0 to match the migration directory.

C4: Team kanban template rewritten for Odoo 19 (<t t-name='card'> with
    semantic <aside>/<main>) instead of legacy <t t-name='kanban-box'>.
    Previous template threw 'Missing card template' at render.

IMPORTANT FIXES:

I1: SO state=sent Confirm button (id='action_confirm') now also gated
    to group_fp_sales_manager. Previously only the state=draft button
    was gated; Sales Reps could send-and-confirm via the secondary path.

I2: Designated Officials picker domain uses all_group_ids (transitive)
    instead of group_ids (explicit only). Owner users now correctly
    appear as eligible CGP DO candidates via the implied_ids chain.

I3: test_menu_visibility.py compliance hub xmlid corrected to
    fusion_plating.menu_fp_compliance_hub (was
    fusion_plating_compliance.menu_fp_compliance_hub which doesn't exist
    -- the hub menu is defined in core's fp_menu.xml). Tests were
    silently skipTest-ing.

I4: _inverse_plating_role chatter audit reads old role from DB via SQL
    (bypasses cache) so 'old -> new' displays actual values, and
    short-circuits no-op writes.

I5: _FP_ROLE_MAPPING_RULES reordered: cgp_designated_official fires
    BEFORE admin/uid_1_or_2 so admin+DO users keep the capability_delta
    marker that triggers res.company.x_fc_cgp_designated_official_id
    auto-set during migration.

I6: _cron_purge_expired_migrations skips groups with active users
    instead of unlink-ing unconditionally. Defense against rollback
    safety being bypassed by manual role assignments post-migration.

CLAUDE.md updated with 3 new durable rules (13b kanban card template,
13c group_ids vs all_group_ids, 13d post_init_hook only on install).

+"""Phase H: fire role-migration preview creation on `-u fusion_plating`.
+
+Odoo 19's `post_init_hook` ONLY fires on fresh install — never on
+upgrade. So on entech (and any other already-installed deployment),
+`-u fusion_plating` after this branch lands would otherwise leave the
+post_init_hook's `_fp_post_init_role_migration` un-fired and the
+migration preview never created.
+
+This migration script bridges that gap: on every `-u` that crosses
+this version boundary, it invokes the same idempotent helper. The
+helper short-circuits if a preview is already pending or already
+applied + all users migrated, so re-running is safe.
