NH: capture version links for bills carried over from prior session year

[alexkost819]

Summary

• NH bills carried over from a prior session year (LSR keeps that year's prefix, e.g. 25-0059 while being scraped as part of session 2026) never appear in NH's LsrsOnly.txt bulk-data dump for the current session, so versions_by_lsr had no id to build a billinfo.aspx page from — the scraper fell into a warn-only branch, leaving these bills with zero version/document links, including bills that became law (HB113, HB565, SB564, HB661, SB522, SB49, SB189, HB348 were the reported examples).
• scrape_from_web already had a working fallback for exactly this case: query the legacy docket page directly by LSR + session year (no numeric id required). Extracted that logic into scrape_versions_from_docket and wired it into the main bulk-data path's missing-id branch, instead of just logging a warning.
• This is a distinct failure mode from PR NH: missing version fix #3508 (which fixed a required time-based query param on GET requests) — that fix is intact and unrelated; this gap was simply never wired up in the primary bulk-data path.

Verification

Reproduced against NH's live site: all 8 reported became_law examples had LSRs entirely absent from LsrsOnly.txt (or, for SB564/SB522, already had a version id but that's a separate/already-working path). Confirmed bill_status/legacy/bs2016/bill_docket.aspx?lsr=<lsr>&sy=<session> returns real version links for these bills directly.

Ran a full 2026-session scrape before and after the fix (same code otherwise):

	bills	zero versions + zero documents
before	1387	232
after	1387	1 (HR48 — genuinely has no text filed on NH's site)

All 8 reported example bills have version links after the fix.

Example: HB113

Before — versions: [], only the generic search-page source:

{
  "identifier": "HB113",
  "versions": [],
  "documents": [],
  "sources": [
    { "url": "https://gc.nh.gov/bill_Status/advanced.aspx", "note": "" }
  ]
}

After — introduced, amendment, and engrossed versions all captured, each with HTML/PDF links:

{
  "identifier": "HB113",
  "versions": [
    {
      "note": "Introduced",
      "links": [
        { "url": "https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?sy=2026&v=HI&id=65&txtFormat=html", "media_type": "text/html" },
        { "url": "https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?sy=2026&v=HI&id=65&txtFormat=pdf", "media_type": "application/pdf" }
      ]
    },
    {
      "note": "Amendment: #2026-0541h",
      "links": [
        { "url": "https://gc.nh.gov/bill_status/legacy/bs2016/billtext.aspx?sy=2026&txtFormat=amend&id=2026-0541H", "media_type": "application/pdf" }
      ]
    },
    {
      "note": "Ought to Pass",
      "links": [
        { "url": "https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?sy=2026&v=SP&id=65", "media_type": "text/html" },
        { "url": "https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?sy=2026&v=SP&id=65&txtFormat=pdf", "media_type": "application/pdf" }
      ]
    }
  ],
  "documents": [],
  "sources": [
    { "url": "https://gc.nh.gov/bill_Status/advanced.aspx", "note": "" }
  ]
}

Before/after scrape output

Full NH 2026-session scrape output, before and after the fix:

• nh_before.zip
• nh_after.zip

Test plan

• python3 -m py_compile scrapers/nh/bills.py
• Full NH 2026-session scrape run before and after the fix, compared bill counts and zero-version/document counts
• Confirmed all 8 reported became_law example bills now have version links

Looks good to me, merging
