chore(innkeeper): upgrade bcrypt to 5.x and add 72-byte compat

[PatStLouis]

Summary

Upgrades bcrypt from 4.2.1 to 5.x in the traction-innkeeper plugin and keeps the app working under bcrypt 5’s 72-byte password limit.

Changes

• bcrypt: Bumped to ^5.0.0 in plugins/traction_innkeeper/pyproject.toml.
• Bcrypt 5.x compatibility: Added bcrypt_compat.py with limit_for_bcrypt() and use it in utils.py and tenant_manager.py so all inputs to hashpw/checkpw are capped at 72 bytes (bcrypt 5.x raises ValueError for longer inputs; 4.x truncated silently).
• Plugin refs: multitenant-provider and connections (acapy-plugins) are set to rev = "main" because 1.4.0 pins bcrypt 4.x and would conflict with bcrypt 5.x. Only these two plugins are on main; no other acapy-plugins were changed.
• Tests: New test test_limit_for_bcrypt_long_password; all 249 innkeeper tests pass with ruff lint/format and coverage.

Note on rev = "main"

Using main is temporary until the acapy-plugins repo has a release that uses bcrypt ^5.0.0 for multitenant_provider and connections. Once that release exists, we should switch these dependencies back to a tag (e.g. rev = "1.5.1") instead of main, so the innkeeper depends on a stable release instead of the current main branch.

I switched the PR over to manual reservation approval and confirmed the generated password works all good. Tenant creation, Login and API keys work
