[BUG] Hoist geometry queries out of pre-alloc loops

[camUrban]

Description

Panel topology is invariant across time steps, so querying every time step's geometry during wake pre-allocation and progress bar estimation is redundant. Use step-0 geometry once instead.

Motivation

This fixes an incompatibility with the coupled solvers, whose future steps do not exist at pre allocation time.

Relevant Issues

Related to Issue #28 (being addressed in PR #156) and Issue #66.

Changes

• Pre-allocate wake arrays and perform progress bar estimation without iterating across all time steps.

Dependency Updates

None.

Change Magnitude

Minor: Small change such as a bug fix, small enhancement, or documentation update.
