The mail-related test suites now run after installation, making checks closer to real development and automated build conditions. This helps catch performance regressions and unexpected database query increases earlier, without changing business functionality.

- take advantage of runbot multi-build capabilities
- get similar result when running them locally during dev
- better detect when other modules add extra queries

Query counts are split in the base value (testing with just test_mail installed) + the extra modules overhead.

This change makes it easier for developers and partners to customize how Point of Sale XML output is prepared without replacing a larger piece of code. It should reduce maintenance effort for custom POS implementations while preserving existing behavior for users.

Before, extending the xml rendering environment was a matter of overriding the
whole method.

This commit enables a clean extenstion point to alter the rendering dict in
the mean time till a thourough refactoring in the near future according to the
new js guidlines.

**Description of the issue/feature this PR addresses:**
- Missing (clean) extension point made alterations to the xml rendering context a real pain

**Current behavior before PR:**
- Unclean extension forces to rewrite the whole method.
- Maintainability of downstream code is suboptimal.

**Desired behavior after PR is merged:**
- Clean extension is possible
- (As if the this js code was already refactored according to the new style)


**Note:** Please do not close, even if not immediately accepted (`wishlist` tag). This PR is meant to be carried along and actively maintained, until this semantic will be completed this way or another.

The manufacturing planning screen now shows replenishment limits as inclusive values, using “less than or equal to” instead of “less than.” This makes the minimum and maximum replenishment guidance match the actual business rules and reduces confusion when reviewing supply needs.
