Fix onclick handlers breaking on source names with special chars

[mbuckingham74]

Summary

• Fixes JavaScript "Unexpected end of input" errors on Configure Source page
• The |tojson filter outputs JSON with double quotes like "Kodiak Area Native Association (KANA)"
• When placed inside an HTML attribute that also uses double quotes, the HTML parser sees the first " and ends the attribute early
• Added |e filter to HTML-escape the quotes to "

Root Cause

<!-- Before (broken): -->
onclick="showScrapeModal("Kodiak Area Native Association (KANA)", true)"
                        ^ HTML attribute ends here!

<!-- After (fixed): -->
onclick="showScrapeModal(&quot;Kodiak Area Native Association (KANA)&quot;, true)"

Files Changed

• configure_source.html - 3 showScrapeModal calls
• partials/generated_scraper.html - 1 showScrapeModal call
• partials/source_list.html - 1 openScrapeModal call

Test plan

• Go to Configure page for "Kodiak Area Native Association (KANA)" - source 39
• Verify no JS console errors
• Verify "Run Scraper Now" buttons work
• Verify "Scrape" button on dashboard works for sources with special chars
