fix(13): use AI-estimated field sizes with type bounds, stricter no-inline-text rule

Browse Source 
- Replace fixed 144x36 with AI widthPct/heightPct clamped to per-type min/max
  (signatures 100-250x20-40pt, initials 36-80x16-28pt, date 60-130x14-24pt, text 60-280x14-24pt)
- Prompt: explicit 'no inline body text' rule — if text is part of a sentence, skip it
- Prompt: widthPct should match visual underline width, heightPct kept thin (~2-2.5%)

WHAT TO PLACE FIELDS ON: WHAT TO PLACE FIELDS ON (only these):
- Blank underlines: ____________ - Visible blank underlines: ____________ (a horizontal line with nothing on it)
- Labeled blanks: "Name: ______", "Address: ______", "Price: $______" - Labeled blank lines: "Name: ______", "Address: ______", "Price: $______"
- Signature lines with labels like "(Seller's Signature)", "(Buyer's Signature)", "(Agent)" - Signature lines labeled "(Seller's Signature)", "(Buyer's Signature)", "(Agent)", etc.
- Date lines labeled "(Date)" or with a date underline - Date underlines labeled "(Date)" or similar
- Initials boxes: "[ ]" or "_____ Initials" or small boxes at page bottoms/margins - Initials boxes: small "[ ]" or "____" next to "Initials" labels, usually at page bottom margins
WHAT NOT TO PLACE FIELDS ON: WHAT NOT TO PLACE FIELDS ON — STRICT:
- Paragraph body text, instructions, legal boilerplate - ANY paragraph body text, even if it contains an address, name, or value inline
- Headings and section titles - Document title, headings, section numbers
- Printed values that are already filled in (e.g. a pre-printed address in the document body)
- Descriptive or instructional text
- If the text is part of a sentence or clause, do NOT place a field on it

POSITIONING: POSITIONING AND SIZING:
- xPct and yPct are percentages from the TOP-LEFT of that specific page image - xPct and yPct are percentages from the TOP-LEFT of that specific page image
- Place the field AT the blank line, not above or below it - Place the field AT the blank underline — align it to sit on top of the line
- For a line like "Buyer's Signature __________ Date _______", place a client-signature at the signature blank's x/y and a date field at the date blank's x/y — they are separate fields on the same line - For a row like "Signature __________ Date _______", create TWO separate fields: one for the signature blank and one for the date blank, each at their own x position
- widthPct: match the visual width of the underline — short blanks get small widths, long signature lines get wider
- heightPct: keep fields thin — signature/text ~2.5%, initials/date ~2%
- Do NOT place checkbox fields - Do NOT place checkbox fields
