Cleanse medication names to title case and normalize legacy rows

[replicant1]

What this PR does

• Cleanses medication brandName and activeIngredient into trimmed, single-spaced title case.
• Applies cleansing in both add flows:
  • Add Medication
  • Add Script (including OCR-prefill and resolution path)
• Enforces cleansing at the data boundary in MedicationRepository.add(...).
• Adds retrospective cleanup for existing rows via cleanseExistingMedicationNames() on app startup.
• Refines edge-case casing rules for medication tokens:
  • release abbreviations: XR, SR, CR, MR, IR, ER, XL, LA, EC, DR, CD, OD, PR
  • chemical abbreviations: HCl, HBr
  • units: mg, mcg, g, kg, ml, l
  • roman numerals: I..X

Verification

• Ran focused JVM tests:
  • :app:testDebugUnitTest --tests "com.example.aitoui.data.MedicationNameCleaningTest"
• Installed updated debug build on attached Pixel 3 and launched app to trigger startup cleanup.
• Verified medication rows are title-cased after cleanup.

Pull request overview

This PR standardizes how medication brandName and activeIngredient are stored/displayed by normalizing them to trimmed, single-spaced title case, and retroactively cleaning legacy rows on app startup to keep existing data consistent.

Changes:

• Added String.cleanMedicationName() and Medication.cleaned() to normalize medication name fields (including special-case tokens like XR/SR, HCl/HBr, units, roman numerals).
• Enforced normalization at the repository boundary (MedicationRepository.add(...)) and added a startup cleanup pass for existing rows.
• Applied normalization in add flows (Medication + Script, including OCR-prefill) and added unit tests for the normalization rules.
