feat(configurator): 19.0.22.1.0 — recipe-driven orders + auto-sync to part

Four customer-feedback fixes (G1-G4):

G1 — Part cell display redundancy. fp.part.catalog.display_name was
showing 'PART (Rev X) — Name' which duplicated with my Part cell widget's
separately-rendered revision + name rows. Added @api.depends_context
('fp_express_part_picker') to _compute_display_name: when the context
flag is True, display_name returns JUST the part_number. The Express
view passes the flag on the part_catalog_id field, so the picker shows
'9876699373' and the widget's row 2/3 show the rev + name.

G2 — Material/Process Tag is now the order's RECIPE, not a free-text
shop tag. Converted material_process from Char to Many2One(fusion.
plating.process.node) with domain [('node_type','=','recipe')] on both
fp.direct.order.wizard AND sale.order. Pre-migration (19.0.22.1.0/
pre-migrate.py) drops the old VARCHAR column so Odoo recreates as
INTEGER FK. Per dev-stage policy, old tag data is dropped.

G3 — Auto-apply order recipe to every line. New onchange
_onchange_material_process_apply_to_lines on the wizard: when the
header recipe is picked / changed, propagate to every line's
process_variant_id (unless the line has an explicit per-line override
that doesn't match the previous header value).

Plus an override on fp.direct.order.line.create that seeds new lines'
process_variant_id from wizard.material_process. So a newly-added
line auto-inherits the order's recipe.

G4 — Auto-sync line edits back to the part catalog. New
_fp_sync_to_part method called from create() + write() on
fp.direct.order.line. Tracked fields:
- line_description     → part.default_specification_text
- bake_instructions    → part.default_bake_instructions
- thickness_range      → part.x_fc_default_thickness_range
- masking_enabled      → part.default_masking_enabled
- process_variant_id   → part.default_process_variant_id

Future orders for the same part will auto-pull these updated defaults
via the existing _onchange_part_default_thickness chain. Last-write-
wins semantics across concurrent edits (acceptable per dev-stage).
