Answer 1

The error is in this line
<field name="arch" type="xml" />
You closed the tag while you really should not. Within this tag the actual XML body should be.
<record id="todo_timesheet_line_tree" model="ir.ui.view">
<field name="inherit_id" ref="hr_timesheet.hr_timesheet_line_tree" />
<field name="model">account.analytic.line</field>
<field name="arch" type="xml">
<field name="task_id" position="after">
<field name="priority" />
</field>
<field name="company_id" groups="base.group_multi_company" position="before">
<field name="gov_department" />
<field name="priority" />
<field name="date_deadline" />
</field>
</field>
</record>
