feat: add product type filter

Address request #92
Feature: Add Token Filtering by Product Type

This PR introduces the ability for users to filter tokens by their productType. The filtering functionality enhances the user experience by allowing users to narrow down token views based on specific categories.

Details:

• Supported productType values with examples:
  • all: Displays all tokens (e.g., *).
  • real_estate_rental: Filters tokens related to rental properties (e.g., 9943 Marlowe St, Detroit, MI 48227).
  • equity_token: Filters tokens representing equity holdings (e.g., RWA Holdings, Neuchatel, NE, Suisse).
  • loan_income: Filters tokens related to income from loans (e.g., LOAN 18 Bristol Villa Buenaventura, El Chiru, Cocle, Panama).

This feature was requested by @Baptiste-Yucca in #92

Note as Equity tokens all been part of other assets section. Selection of equity token filter automatically switch them on

Looks good to me.
There's a strange behaviour which occurs when unchecking a previously checked value: it filters out everything.
But it exists on all filters and this is beyond the scope of thisPpR
