Fix additional nesting depth issues across multiple files 
Extracts nested logic into helper functions to comply with Credo
requirements (max nesting depth 2):

- data_builder.ex: Extract historical packet distance filtering
  (filter_historical_by_distance/3, packet_far_enough_from_most_recent?/3)
  Reduces depth 5 -> depth 3

- streaming_packets_pubsub.ex: Extract subscriber message sending
  (send_to_subscriber_if_alive/3)
  Reduces depth 4 -> depth 2

- aprs_symbol.ex: Extract symbol code calculation
  (get_symbol_code_ord/1)
  Reduces depth 3 -> depth 2

- mobile_channel.ex: Extract subscription bounds update
  (update_subscription_bounds/2)
  Reduces depth 3 -> depth 2

- core_components.ex: Extract SVG tag class insertion
  (add_class_to_svg_tag/2)
  Reduces depth 3 -> depth 2

- info_live/show.ex: Extract row mapping for database queries
  (map_digipeater_row/2, map_station_heard_row/2)
  Reduces depth 3 -> depth 2 (2 instances)

Also updates .sobelow-skips with new line numbers from code changes.

Fixes 7 Credo nesting depth issues (2 remaining)

Reduce cyclomatic complexity in aprs_symbol and database_metrics 
Simplify complex functions:
- aprs_symbol.ex: Simplify get_overlay_base_table_id (all cases return "1")
- database_metrics.ex: Extract metric reporting helpers to reduce nesting

Add Redis-based distributed caching and rate limiting 
This commit introduces a dual-mode caching and rate limiting system that can use
either Redis (for distributed deployments) or ETS/Cachex (for single-node setups).

Key changes:
- Add Cache abstraction layer that automatically switches between Redis and Cachex
- Implement RedisCache module with full distributed cache functionality
- Implement RedisRateLimiter with sliding window algorithm for accurate rate limiting
- Add RateLimiterWrapper to provide unified API for both implementations
- Update application startup to conditionally use Redis when REDIS_URL is set
- Migrate all cache operations to use the new Cache abstraction
- Support graceful fallback to ETS-based solutions when Redis is unavailable

The system automatically detects Redis availability via REDIS_URL environment
variable and switches between implementations without code changes. This enables
proper distributed caching and rate limiting in Kubernetes deployments while
maintaining backward compatibility for development environments.
