Steps to reproduce:
-------------------------------------------
1. Install the Timesheet module with demo data
2. Go to any FSM task > set allocated hours to 20h
3. Fill the timesheet for the same task for 10h
4. Navigate to FSM > My Tasks > Gantt view

Observation:
-------------------------------------------
Look at the task on the Gantt chart. The shading is barely visible because it covers only 0.5% of the bar, not 50%

Issue:
-------------------------------------------
In the commit
https://github.com/odoo/odoo/pull/137570/changes/4a93d9aee957dd3feb3db0cb69eb3b8f0f4a4683 The progress field computation was changed from storing percentage values (0-100) to storing decimal values (0-1). Specifically, the `_compute_progress_hours` method was modified. This change was made to standardize the progress field storage format, with the understanding that the UI layer would multiply by 100 when displaying the value. While most views (form, list, kanban, etc.) were updated to multiply the progress by 100 for display purposes, the Gantt view's pill progress bar was missed.

Solution:
-------------------------------------------
Overrides the `enrichPill` method to multiply the `_progress` value by 100 before it's passed to the template. This ensures the Gantt pill progress bars display correctly without modifying the core web_gantt module.

Steps to reproduce:
----------------------------------------
1. Install `industry_fsm_sale` and `base_automation` modules
2. Create a product with:
    * Type: Service
    * Create on order: Task
    * Project: Field Service
3. Create an automation rule with:
    * Model: Sales order
    * Trigger: Incoming message
4. Create and confirm a sale order with this product
5. Add another product to the SO via the catalog view:
    * Change the quantity to 2 or more

Observation:
----------------------------------------
Traceback occurs:
```
  File '/home/odoo/src/odoo/addons/base_automation/models/base_automation.py', line 871, in _message_post
    message_sudo = message.sudo().with_context(active_test=False)
AttributeError: 'bool' object has no attribute 'sudo'
```

Root Cause:
----------------------------------------
* Catalog qty change calls `set_fsm_quantity()` method
* Setting `fsm_quantity` triggers its inverse `_inverse_fsm_quantity()`, which writes the new qty to the SOL, but passes `fsm_no_message_post=True` in context to suppress chatter noise
https://github.com/odoo/enterprise/blob/ac5d670832a5e0db714c0bd056e1406b50bb4c17/industry_fsm_sale/models/product_product.py#L72-L83
* `sale.order.line.write()` detects a qty change on a confirmed order and calls `_update_line_quantity()`, which posts a message on the parent sale order
* FSM's `message_post` override sees the context flag and returns `False`
* When `base_automation` has an `on_message_received` rule on `sale.order`, it wraps `message_post` at registry load time. That wrapper calls `sudo()` on whatever `message_post` returns, Which was `False`

Solution:
----------------------------------------
Return `self.env['mail.message']` (empty recordset) instead of False, it's still falsy, but it's a proper ORM object that `sudo()` can be called on
