V105: CRM tables.

Two tables supporting the upcoming phoenix_kit_crm plugin:

phoenix_kit_crm_role_settings

Tracks which user roles have opted into the CRM module. One row per role; the FK cascades on role deletion so no orphan cleanup is needed.

• role_uuid UUID PRIMARY KEY — FK → phoenix_kit_user_roles(uuid) ON DELETE CASCADE
• enabled BOOLEAN NOT NULL DEFAULT false — opt-in flag; false by default so existing roles are unaffected until an admin explicitly enables CRM.
• inserted_at, updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()

phoenix_kit_crm_user_role_view

Per-user, per-scope view preferences for CRM tables (column selection, ordering, active filters). One row per (user, scope) pair; scope values are strings like "role:<uuid>" or "companies".

• uuid UUID PRIMARY KEY DEFAULT uuid_generate_v7()
• user_uuid UUID NOT NULL — FK → phoenix_kit_users(uuid) ON DELETE CASCADE
• scope VARCHAR(100) NOT NULL — e.g. "role:<uuid>", "companies"
• view_config JSONB NOT NULL DEFAULT '{}' — arbitrary UI preferences blob
• inserted_at, updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
• UNIQUE (user_uuid, scope) — one preference row per user/scope pair
• Index on (user_uuid) for per-user lookups

All operations are idempotent.
