feat(entrypoints): project the report to Neo4j, count what never resolved, detect odoo

[rahlk]

Closes #177. Three gaps from one Odoo run:

• :PyApplication carries entrypoint_frameworks (string[]) and entrypoint_report_json (the whole PyEntrypointReport), always present, so a graph consumer can tell "no entrypoints" from "the pass found nothing". Additive graph-catalog change; schema.neo4j.json regenerated.
• PyEntrypointReport.unresolved had no writer and read {} on every run. It now counts, per written spelling, the decorators and base classes that neither Jedi nor the module's import table could name.
• Decorator matching falls back to the module's import table when Jedi cannot resolve the decorator, the way base-class matching already did. from odoo import http plus @http.route matches odoo.http.route with odoo not importable, which is every --no-venv run. odoo joins the shipped rules: @http.route methods (route from the first positional, one or a list; methods from methods=, default GET) and http.Controller subclasses.

Verified on a fixture under --no-venv: Ctl.index detected as odoo.route with route /x, Ctl as odoo.controller, report lists odoo.
