fix: keep string tag values on HTML select labels

[sankalpsthakur]

📌 Description

Select labels went blank when the bound tag was a string. parseFloat then Number both yield NaN, so select.value never matched an option. Fall back to the raw signal value after those coercions fail.

• What problem does this solve? String-valued select options show no selected label.
• What was changed? HtmlSelectComponent.processValue keeps non-numeric string values.
• Why is this needed? Number/boolean tags still work; strings were dropped.
