Subject: [PATCH] feat(community_membership): tier model, res.partner
 extension, settings (Session 1-A)

Adds the membership foundation: community.membership.tier (admin-configurable
tiers, each auto-creating a linked invoicing product), res.partner membership
fields (member ID, tier, state, family grouping, volunteer tracking), and a
res.config.settings page (org name, member-ID format, renewal offsets, portal
toggle) - all backed by ir.config_parameter so nothing is hardcoded.

Member IDs are generated on activation via a configurable format string
({year}/{seq}) resolved against an ir.sequence. Adds the Membership Manager
group/menu and views (tier list/form, partner form tab, list columns, search
filters, settings page).

Along the way, hit two real Odoo 19 API changes vs. older tutorials/docs:
res.groups.category_id was replaced by privilege_id -> res.groups.privilege,
and module settings pages now use the <app>/<block>/<setting> pattern
inherited from base.res_config_settings_view_form rather than raw divs.

Verified by upgrading the module against a live Odoo 19 + Postgres 16
container: installs clean, all 4 tests pass (tier->product creation, member
ID generation on activation, one-time/lifetime tiers never expire,
configurable ID format), and the module still installs cleanly for its
dependents (community_benefits, tncsc_deployment).
