Feat/filter rule type select

[FaustUser]

What This PR Changes

This PR improves the rule editor UX for rule type and payload selection.

Included Improvements

• replaced the plain Rule Type dropdown with a filterable selector
• added inline help tooltips with descriptions for each rule type
• localized rule type descriptions for all supported UI languages
• fixed dropdown overflow so filtered results stay inside the scrollable list
• added validated payload selectors for GEOIP, SRC-GEOIP, and GEOSITE
• payload values are now loaded from local geoip.dat and geosite.dat
• validation now allows only values that actually exist in the corresponding Geo database
• improved selector search behavior to avoid irrelevant fuzzy matches
• optimized large payload lists to prevent UI freezes when opening or filtering selectors

Technical Details

• added a main-process utility to read available entries from local Geo databases
• exposed Geo database entries to the renderer through IPC
• switched combobox search from built-in fuzzy filtering to explicit controlled filtering
• limited rendered search results to reduce expensive list rendering in large datasets

Result

The rule editor is now faster and more predictable:

• rule types are easier to find
• GeoIP / GeoSite payloads can be selected from valid database-backed values
• invalid Geo payloads are prevented
• dropdowns no longer overflow visually
• opening payload selectors no longer causes noticeable UI hangs

Verification

• npm.cmd run typecheck
