f413a24408 Fix API bugs exercised by test/deep_api_bugs.cpp 
- api_fpa.cpp: add RETURN_Z3(nullptr) after SET_ERROR_CODE in Z3_mk_fpa_sort to prevent fall-through to mk_float_sort with invalid params
- api_seq.cpp: add null check for str in Z3_mk_string; add null check for str when sz>0 in Z3_mk_lstring; add lo<=hi validation in Z3_mk_re_loop
- api_array.cpp: add explicit n==0 validation in Z3_mk_array_sort_n
- api_solver.cpp: rename local variable 'c' to avoid shadowing Z3_context param in Z3_solver_propagate_created/decide/on_binding; move init_solver call inside file-exists branches of Z3_solver_from_file
- api_ast.cpp: add null check for target in Z3_translate; add null check for _from/_to arrays when num_exprs>0 in Z3_substitute
- api_model.cpp: add CHECK_NON_NULL(m) in Z3_add_func_interp; add CHECK_NON_NULL(a) in Z3_model_get_const_interp; add null check for target in Z3_model_translate
- api_opt.cpp: add null check for weight string in Z3_optimize_assert_soft

b8d6952e9e Enable som (sum of monomials) in optimizer simplification 
The optimizer's simplification pass did not expand products of sums
into sum-of-monomials form. This caused mathematically equivalent
expressions like (5-x)^2 vs (x-5)^2 to simplify into different
internal forms, where the former produced nested multiplies
(+ 5.0 (* -1.0 x)) that led to harder purification constraints
and solver timeouts.

Enabling som=true in the first simplification tactic normalizes
polynomial objectives into canonical monomial form, making the
optimizer robust to operand ordering.

ce7c7f458e Add max_rev test: BNH with reversed argument order in f1/f2 
Same as test_bnh_optimize but constructs f1 and f2 with reversed
parameter order in mk_add, mk_mul, mk_sub calls. Exposes optimizer
sensitivity to expression structure.
