Migration of mis_builder_budget from 19.0 to 20.0, as per the migration guide.

Part of #843. Depends on #842 (mis_builder), referenced from test-requirements.txt in a [DON'T MERGE] commit, so the "Detect unreleased dependencies" check fails on purpose. That commit must be dropped once #842 is merged.

Changes:

• Bump version to 20.0.1.0.0 and make the module installable.
• Migrate the four security/*.xml files (ir.model.access and global ir.rule records) to security/ir.access.csv with upgrade_code 19.4-00-ir-access. The xmlids are kept: the multi-company rules become restrictions without group.
• Add migrations/20.0.1.0.0/pre-migration.py, the same as in [20.0][MIG] mis_builder: Migration to 20.0 #842 for mis_builder: it drops the xmlids still pointing to ir.model.access / ir.rule, so that ir.access.csv can load. Without it, a database where those xmlids keep the legacy model fails on update with found record of different model ir.model.access. Tested on a database seeded that way: it fails without the script and updates with it. Not tested yet on a database upgraded from 19.0.
• copy=True on mis.budget.by.account.item.name: since 20.0, Char fields named name are copied with a " (copy)" suffix unless they set copy, so the labels of the items were changed when duplicating a budget. test_copy now checks the labels.
• env.clear() is deprecated in 20.0: replaced by env.transaction.clear() in the tests.
• Stat button icon fa-bars -> menu (Material Symbols).
• New ruff rules: dict() calls to literals (C408) and nested if (SIM102).
• No ClassVar annotations or noqa are added for RUF012 on _inherit. The rule is ignored for Odoo >= 20.0 in the repository template (OCA/oca-addons-repo-template#376, proposed for this repository in Update dependency https://github.com/OCA/oca-addons-repo-template to v1.48 (20.0) #852). Until it is merged, the ruff pre-commit hook reports RUF012 on this module.
• .pre-commit-config.yaml: mis_builder_budget leaves the non-installable list; mis_builder and mis_builder_demo are added, as they are still not installable on 20.0.

The 16 tests pass on a 20.0 database with mis_builder from #842.
