[joaquinbejar]

Issue #257: Update dependencies - zip 7.0, plotly 0.14, positive 0.3.0

Summary

Update the following dependencies to their latest versions:

Dependency	Current	Target	Notes
zip	6.0	7.0	Major version update
plotly	0.13	0.14	Minor version update
positive	0.2.1	0.3.0	Minor version with new features

Changes Required

1. Update Cargo.toml

# Before
zip = "6.0"
plotly = { version = "0.13", default-features = false, features = ["static_export_default"] }
positive = { version = "0.2.1", features = ["utoipa"] }

# After
zip = "7.0"
plotly = { version = "0.14", default-features = false, features = ["static_export_default"] }
positive = { version = "0.3.0", features = ["utoipa"] }

2. Leverage New positive Constants

The positive 0.3.0 crate introduces many new constants that can replace pos_or_panic! calls:

New Constants Available

Positive::THOUSAND	1000.0	pos_or_panic!(1000.0)
Positive::PI	π	pos_or_panic!(3.14159...)
Positive::E	e	pos_or_panic!(2.71828...)
Positive::INFINITY	∞	Max positive value

3. Leverage New positive Methods

New methods that can improve error handling and code quality:

Checked/Safe Conversion Methods

• to_f64_checked() - Returns Option<f64> instead of panicking
• to_f64_lossy() - Returns 0.0 on failure instead of panicking
• to_i64_checked() - Returns Option<i64>
• to_u64_checked() - Returns Option<u64>
• to_usize_checked() - Returns Option<usize>

Checked Arithmetic

• checked_sub(&self, rhs: &Self) -> Result<Self, PositiveError> - Safe subtraction
• saturating_sub(&self, rhs: &Self) -> Self - Returns ZERO instead of negative
• checked_div(&self, rhs: &Self) -> Result<Self, PositiveError> - Safe division
• sqrt_checked(&self) -> Result<Positive, PositiveError> - Safe square root

Utility Methods

• sub_or_zero(&self, other: &Decimal) -> Positive - Subtraction with zero floor
• sub_or_none(&self, other: &Decimal) -> Option<Positive> - Subtraction returning None if negative
• is_multiple_of(&self, other: &Positive) -> bool - Check if value is multiple
• clamp(&self, min: Positive, max: Positive) -> Positive - Clamp value to range
• round_to_nice_number(&self) -> Positive - Round to aesthetically pleasing number

Implementation Tasks

Phase 1: Update Dependencies

• Update Cargo.toml with new versions
• Run cargo build to check for breaking changes
• Fix any compilation errors from API changes

Phase 2: Replace Constants

• Search for pos_or_panic!(5.0) and replace with Positive::FIVE
• Search for pos_or_panic!(30.0) and replace with Positive::THIRTY
• Search for other numeric constants that match new Positive constants
• Focus on production code first, then tests

Phase 3: Adopt New Methods

• Replace .to_f64().unwrap() patterns with .to_f64_lossy() where appropriate
• Use checked_sub and saturating_sub for safer arithmetic
• Use checked_div to avoid division by zero panics

Phase 4: Testing

• Run full test suite
• Verify make lint-fix passes
• Verify make pre-push passes

Acceptance Criteria

• All dependencies updated to target versions
• No compilation errors
• All tests pass
• pos_or_panic! calls replaced with constants where applicable
• New safe methods adopted where beneficial
• make lint-fix passes
• make pre-push passes
