Fixed formula class names according to Blueprints standards based on feedback from @SZeltaat.

Changes Made

Class Name Changes (lowercase n in class names only)

Updated 8 class names to conform to Blueprints naming standards:

  1. SubForm3Dot282930MuSubForm3Dot28And29And30Mu
  2. Form4Dot3NCheckExecutionTolerancesForm4Dot3nCheckExecutionTolerances
  3. Form4Dot4NCheckExecutionTolerancesForm4Dot4nCheckExecutionTolerances
  4. Form6Dot10abNStrengthReductionFactorForm6Dot10abnStrengthReductionFactor
  5. Form6Dot11abcNCompressionChordCoefficientForm6Dot11abcnCompressionChordCoefficient
  6. Form6Dot3NShearCapacityWithoutRebarForm6Dot3nShearCapacityWithoutRebar
  7. Form6Dot57NNuPrimeForm6Dot57nNuPrime
  8. Form6Dot37Dot38MomentReductionForm6Dot37And38MomentReduction

Docstring and Label Corrections

Based on feedback, reverted all docstring, label, and reference changes back to uppercase N:

  • File headers: "Formula 6.3N" (not "Formula 6.3n")
  • Labels: label = "6.3N" (not label = "6.3n")
  • Class docstrings: "formula 6.3N" (not "formula 6.3n")
  • Formula references: "Expression (6.3N)" (not "Expression (6.3n)")
  • LaTeX method comments: "formula 6.3N" (not "formula 6.3n")

Supporting Updates

  • Updated all relevant test file imports and class references
  • Updated documentation files in docs/codes/eurocode/ to match new class names while preserving formatting
  • Verified all imports work correctly with new class names and correct labels

The key insight is that only class names use lowercase "n" while all documentation, labels, and references correctly use uppercase "N" to match the official Eurocode specifications.

<issue_title>[🐞 Bug]: Fix invalid formula namings</issue_title>
<issue_description>### Checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of Blueprints.

Issue description

As detected in #667 some class names are not according to Blueprints standards. The naming has to change.

Reproducible example

See #667

Expected behavior

Adding And where multiple sub formulas are implemented in one class
Change N to n

to

class Form6Dot37And38MomentReduction(Formula):

Also follow these rules:

  • Do not change the names in the doc-strings. Those are correct. This changes concern only the standard convention of Blueprints for naming classes.
  • Make changes also in the relevant trest files
  • Make changes also in the relevant files in docs/codes/eurocode. Keep the formatting intact.

You're right! I've reverted all the docstring changes back to uppercase N while keeping the class name changes as requested. The docstrings, labels, and formula references now correctly use uppercase N (like "6.3N", "6.57N", "6.11a/b/cN") while only the class names use lowercase n (like Form6Dot3nShearCapacityWithoutRebar).

Done! I've reverted all the docstring changes back to uppercase N as requested. All file headers, labels, class docstrings, formula references, and LaTeX method comments now correctly show uppercase N (matching the Eurocode specifications) while keeping the class name changes to lowercase n.
