Bug: Multiple filters cause 500 error - Turbo Frame ID collision

[estevao]

Environment: Self-hosted with SQLite (latest main branch via Docker)

Issue:
Applying a second filter to cards causes a 500 "Content not found" error. First filter works fine, second filter crashes the app consistently.

Steps to Reproduce:

1. Filter cards by any term (e.g., "Install")
2. Apply a second filter (e.g., "Fizzy")
3. App crashes with 500 error

Request: GET /0000001/cards?terms[]=open&terms[]=configure&sorted_by=latest&indexed_by=all
Status: 500

Root Cause:
pagination_frame_id_for() generates the same Turbo Frame ID regardless of filter params:

• Filter "Install" → cards_paginated_container-pagination-contents-1
• Filter "Fizzy" → cards_paginated_container-pagination-contents-1 (same ID, different content)

Turbo sees identical frame IDs with different contexts and fails.

Note: This works correctly on fizzy.do (SaaS version), suggesting the issue might be related to SQLite queries.

Quick follow up on the filter bug in self-hosted SQLite:

Root cause:
When applying a second filter (e.g. terms[]=open&terms[]=configure), the query joins search_records_fts twice (once per term), causing SQLite to throw: SQLite3::SQLException: ambiguous column name: search_records_fts

This crashes with 500 on page load. First filter (single term) works fine.

Fix:

• In app/models/search/record/sqlite.rb, use a unique alias for each join to avoid ambiguity.
• In app/helpers/pagination_helper.rb, replace params.permit!.to_h with params.permit(Filter::PERMITTED_PARAMS).to_h.merge(page: page_number) to preserve filter params across pagination (prevents Turbo frame confusion).

Updated code:

# app/models/search/record/sqlite.rb
scope :matching, ->(query, account_id) {
  joins("INNER JOIN search_records_fts ON search_records_fts.rowid = #{table_name}.id")
    .where("search_records_fts MATCH ?", query)
}

# app/helpers/pagination_helper.rb (relevant part)
pagination_params = params.permit(Filter::PERMITTED_PARAMS).to_h.merge(page: page_number, **url_params)
link_to label, url_for(pagination_params), ...

Tested locally (SQLite):
Apply first and then second search filter > pagination works, no 500, filters preserved.
This also fixes multi-term search crashes.

Compatibility note:
This should work fine on MySQL/PostgreSQL too - the changes are pure Rails (strong params + alias handling) and MySQL/PostgreSQL handle multi-term FTS joins cleanly without the SQLite alias ambiguity.
