Reproduction link

Description:
When copying numeric values from Microsoft Excel and pasting them into Univer Sheets, the values are automatically formatted with dots as thousand separators, instead of preserving the original raw number format.
Additionally, Univer interprets the pasted value as text, not as a numeric cell value — which causes issues when performing calculations or data processing.
Screenshots:

Expected behavior

Univer should preserve the original raw numeric value exactly as copied.
The pasted value should be recognized as number type, not text.
Thousand separators should not be added automatically unless applied manually or via formatting rules.

Actual behavior

Pasted numbers are displayed as 516.382.306.730 instead of 516382306730.
The cell is interpreted as text, not a numeric value.
This breaks numeric calculations and sorting behavior.
