feat(odoo_blueprint::extracted::pairing): D-ODOO-EXT-5 — curated-vs-extracted pairing table

Builds the cross-reference table that links every L-doc curated lane
entity (`l{1..15}::*`, `OdooConfidence::Curated`) to its source-extracted
counterpart (`extracted::*::EXT_*`, `OdooConfidence::Extracted`) when
both exist for the same `model_name`.

Outputs:
- `crates/lance-graph-ontology/src/odoo_blueprint/extracted/pairing.rs`
  exposes `pub static CURATED_EXTRACTED_PAIRS: &[OdooEntityPairing]` —
  48 pairings (53 curated model_names × 229 extracted in TIER-1).
- `/tmp/pairings.json` (out-of-tree) records field/method count deltas
  per pairing for human review.

Scanner: stdlib `re` over the generated Rust source; lives in
`tools/odoo-blueprint-extractor/odoo_blueprint_extractor/pairing.py`
with a `pair` CLI subcommand (`python -m odoo_blueprint_extractor pair`).

Const selection rules (both sides):
- Curated: highest field+method count wins (handles indirect-ref files
  like l3.rs that reference separate const slices); alphabetical const_name
  on tie. This correctly picks l9.rs over l3.rs for `account.fiscal.position`
  (17+11 vs 0+0 counted inline fields/methods).
- Extracted: most fields+methods wins (picks richest coverage when a
  model appears in multiple addons, e.g. `uom.uom` in uom.rs preferred
  over account.rs/product.rs/stock.rs appearances).

Side-effect: promoted 17 module-private (`const`) lane entities to
`pub const` in l3.rs, l5.rs, l7.rs, l13.rs so they're accessible
from `crate::odoo_blueprint::<lane>::<CONST>` paths. These consts
were only reachable via the `ENTITIES` slice before; making them pub
is additive (no tests change) and required for the pairing reference.

Most striking deltas (curated savant-relevant subset vs full ORM):
  account.move:      24f/27m → 142f/352m (+118f/+325m)
  account.move.line: 20f/14m → 87f/146m  (+67f/+132m)
  sale.order:        22f/13m → 65f/141m  (+43f/+128m)
  stock.move:        23f/14m → 74f/130m  (+51f/+116m)
  account.tax:        3f/0m  → 36f/113m  (+33f/+113m)

5 curated model_names have NO TIER-1 extracted backing (EXT-6 gap rows):
  hr.contract.type, hr.department, hr.employee, hr.job, stock.valuation.layer
These are TIER-2 addons (hr, account_asset) — expected leakage.

Curated stays canonical on conflict (per BP-1 plan §"merge ordering");
extracted is the audit backing.

Tests: 2 new (`pairing_table_is_well_formed`, `pairing_table_has_expected_size`);
all 199 pre-existing ontology tests stay green (201 total).

Next: D-ODOO-EXT-6 (coverage report — uses this pairing table to
quantify lane-level extracted-backing).

Plan: `.claude/plans/odoo-source-extraction-v1.md`.
